Hello to all fans of electronic homemade products. It’s time to tell you about another homemade product. And today we will talk about the so-called Chizhevsky chandelier.
Recently, there has been a lot of controversy about the benefits and harms of Chizhevsky’s chandelier. It helps some, harms others, and others are indifferent to its effects. To find out who is right and who is wrong, you need to consider each specific case separately. I won’t go into this in this article, but next time.
It has long been proven that negative air ions have a good effect on the entire human body, while positively charged ions depress the body. Measurements were made in forest plantations, which showed that the concentration of air ions can reach, in densely populated thickets, up to 15,000 per cubic centimeter. While in a residential apartment the number of air ions in one cubic centimeter can drop to 25. From all of the above, we can conclude that it is necessary to increase the number of negatively charged ions. To do this, we will need a Chizhevsky chandelier, which we will make with our own hands. Almost 100 years ago, Professor Chizhevsky developed a method of air ionization. He proved that it is negatively charged particles that have a beneficial effect on humans.
DIY Chizhevsky chandelier, diagram and description
Chizhevsky's chandelier consists of two parts. This is the chandelier itself, as it is also called an electroeffluvial chandelier. And a high-voltage converter unit, at the output of which we should get from 25-30 kilovolts.
To make a high-voltage voltage converter, I used the simplest Chizhevsky chandelier circuit. It does not contain transistors or any scarce radio components. The circuit uses a minimum of radio components:
This scheme has become widespread. As a high voltage source, a voltage multiplier is used here, built on 6 high-voltage diodes VD3-VD8, and 6 capacitors C3-C8. Power to the multiplier is supplied from the high-voltage coil Tr1. The mains voltage has two half-waves. One half-wave charges capacitor C1, and the other half-wave opens thyristor VS1. Capacitor C1 is discharged through thyristor VS1 to the primary winding of transformer Tr1. A high-voltage pulse occurs in the transformer, the voltage of which is increased by a multiplier to a voltage of 30 kilovolts.
Device details:
- High-voltage coil B51, or similar
- Thyristor KU202N
- Diode D202K - 2 pieces
- Resistors 33 kilo-ohms, 1 mega-ohm 2 watts
- Resistor 1 kilo-ohm, 7 W
- Capacitor 1 microfarad 400 volts
- Capacitors 390 picofarads, 16 kilovolts -6 pieces
- High voltage diodes, 6 pieces
Now let's take a closer look at the main voltage converter board and the voltage multiplier board. All the main radio components of the device are mounted on the converter dress:
High-voltage coil from a motorcycle, B51-12v. It can be replaced with any other vehicle. You can also use a horizontal scan transformer TVS-110L6 or similar:
Nowadays, it is much more affordable to buy a high-voltage coil from a moped or scooter, for example this one:
It is advisable to use capacitor C1 for voltages below 400 volts, but in my case a capacitor for voltages of 300 volts is used, so far it works flawlessly:
Seven-watt resistor R1, rated 1 kilo-ohm, taken from a tube TV. If you do not have such a resistor, then you can connect several two-watt resistors in parallel, so that you end up with a nominal value of one kilo-ohm:
The remaining radio components are located nearby and are connected by surface mounting:
A correctly assembled voltage converter for a Chizhevsky chandelier should start working immediately. Before the first start-up, the high-voltage wire of the reel should be placed near the common wire at a short distance, approximately 5 mm. If you do not maintain this distance, but make it much larger, say 3-4 cm, then a breakdown of the high-voltage coil inside the bobbin itself may occur. After this, we supply power to the entire circuit, observing safety rules. If the circuit does not start, you should select thyristor VS1. Since thyristors, even from the same batch, have a wide variation in their characteristics, special attention should be paid to the selection of a thyristor.
Attention! Be careful. This high-voltage converter does not have galvanic isolation from the network. Almost all radio components are under mains voltage. To somehow protect yourself, try to apply the phase to the resistor R1, and the zero to the common wire.
To power the chandelier, a voltage of 25 kilovolts to 30 kilovolts is required, and if used in rooms with high ceilings, the voltage must be raised to 50 kilovolts. To provide such a voltage, a multiplier consisting of at least 6 diodes and 6 capacitors is required. Only in this case can you obtain the required voltage. In this regard, it immediately comes to mind to use a high-voltage multiplier, which is used in CRT-type TVs. I also thought for a long time about how to adapt it to Chizhevsky’s chandelier. But, unfortunately, plus voltage is supplied to the aquadag of the kinescope. And in order for us to get negative air ions, we need to apply negative high voltage to the chandelier. And since all high-voltage diodes and capacitors are filled with the same compound, the polarity cannot be changed. So I took some voltage multipliers from the TV and, using light hammer blows, tried to break them and remove the capacitors and diodes. To some extent I succeeded. Where the pins were torn off at the root, we had to solder them. Some fragments of the compound had to be sanded down. As donors I used the following voltage multipliers UN 8.5/25-1.2-A:
As a result, I got this multiplier. A piece of plexiglass was taken as a basis and high-voltage diodes and capacitors were secured using wire clamps:
In order not to make a mistake with the polarity of high-voltage diodes, and to connect them correctly according to the circuit, you need to know in which direction each high-voltage diode conducts current. Unfortunately, it will not be possible to check this with a multimeter, since each diode consists of a large number of washers, single diodes, the internal resistance of each diode is very high and the multimeter will show infinity. To get out of this situation you need to use a megohmmeter. But first, using a conventional diode, you need to determine which terminals of the megohmmeter are positive and which are negative. Then ring each high-voltage diode and mark it with a plus or minus. After this, it will not be difficult to connect capacitors and diodes into one circuit so that we get a high voltage:
Of course, to avoid all this hemorrhoids, you can use normal high-voltage diodes like KTs201G-KTs201E or D1008. But, unfortunately, in my outback it is simply impossible to find them, and in Soviet times it was simply impossible to order via the Internet. Therefore, I decided to use this extraordinary method of obtaining high-voltage diodes and capacitors.
Both assembled boards must be placed in some kind of housing. In this case, a condition must be met - the high-voltage voltage multiplier should be placed at a certain distance from the converter itself. Especially the area of diode VD8 and capacitor C6, since in this place there will be the highest voltage, and an unauthorized breakdown may occur.
DIY Chizhevsky chandelier
The time has come to talk about making the chandelier itself for the ionizer. To effectively ionize air, you need to use pointed needles, which should be located on a certain plane. Of course, ideally, you need to use as much of the radiated surface area as possible. As a base for a chandelier, you can use an aluminum hula hoop with a diameter of up to 1 m. But you must admit, having such a large chandelier in an apartment will be impractical, and it will take up a lot of space. Therefore, I decided to make it more compact, since the main thing in a chandelier is the amount of high voltage, but still the area is secondary. The main rule to follow is the presence of pointed needles. As a result, I ended up with this design:
When making this Chizhevsky chandelier, I followed this scheme:
The base of the perimeter was made of copper wire with a diameter of 2.4 mm. Then wires with a diameter of 1 mm were stretched mutually perpendicularly. The result is a grid with 35 mm cells. Then, sharp needles 45 mm long were soldered into each node of the resulting mesh. I chopped the needles with a chisel, from a motorcycle cable that is used for clutches. Of course, you can use factory-made needles with a ring, but it seemed to me that they would be painfully stiff and not so elastic. Since the needles are made of steel, soldering them is not so easy. To ensure that soldering does not cause difficulties, the tip of each needle must first be tinned with soldering acid, and if you do not have it, then with acetylsalicylic acid (aspirin):
After making the Chizhevsky chandelier, it was time to test it. To do this, we take the emitter itself and hang it from the ceiling. I hang the lighting from the chandelier, about 1 m below it. To isolate the emitter, you need to hang the chandelier itself on a fishing line. We connect a high-voltage wire from a high-voltage converter to the center of the chandelier. Also, in my opinion, power should be supplied to the chandelier according to the following scheme: the phase is supplied to the resistor R1, and the zero to the common wire. In my opinion, this is especially important in an apartment in a reinforced concrete building, since the reinforcement of concrete slabs is essentially ground, and the radiation will be more effective if the network power zero is supplied to the common wire, generally as indicated in the diagram:
Then we supply mains power to the high-voltage converter and check the chandelier in action. During its operation, no odors should be emitted, especially ozone, as well as light gases during corona, which can occur due to poor insulation of high-voltage capacitors or diodes. If you bring your hand to the side of the needles, you feel a slight chill already from a distance of about 20 cm. Honestly, this is an indescribable feeling when there is no wind, but it seems that there is some. If the lights in the apartment are completely turned off, then at the tip of each needle you can see a luminous point through which the discharge occurs. If you bring a low voltage indicator to the bottom side of the chandelier, then the gas discharge lamp in this indicator begins to glow from 80 cm, and if you bring the indicator closer and closer, it lights up brighter.
Although the voltage on the chandelier reaches 30 kW, the current is very small, and it cannot harm others. In order for us to indirectly verify the magnitude of the high voltage, we need to bring a metal object, holding it firmly in our hand, and evaluate the magnitude of the discharge. Based on the length of the arc, you can indirectly judge the magnitude of the voltage by adopting a simple formula that there are 10 kilovolts of voltage per 1 cm, respectively, for 30 kilovolts a distance of about 30 mm is required, which is what I did:
As you can see, the breakdown voltage is at least 25 mm, accordingly the operation of the chandelier will be effective. Practice has shown that it is for this Chizhevsky chandelier, which we made with our own hands, of a small area, that this high-voltage converter is quite effective. The heating of resistor R1 is not so great, it is barely warm. Ignition coil B51 is generally cold. The diodes and capacitors of the voltage multiplier are barely perceptibly warm. Since the therapeutic effect of using the Chizhevsky chandelier occurs within 30 minutes, this converter can be used without fear of overheating for much longer.
Only time can tell how beneficial this device may be for health, or whether, on the contrary, it will harm. So don't be shy, make a chandelier. I hope she adds health. Thank you all for reading to the end, see you again, goodbye everyone.
It is known that negative air ions have a beneficial effect on the human body, while positive ones contribute to rapid fatigue. Numerous studies have shown that the air of forests and meadows contains from 700 to 1500, and sometimes up to 15,000 negative air ions per cubic centimeter. In residential premises, their number sometimes drops to 25 per 1 cm3.
Anyone can increase the saturation of the air in their home with air ions by making themselves an ionizer consisting of an electroeffluvial chandelier and a high-voltage converter. An electroeffluvial chandelier (see figure) is an emitter of negative air ions. It consists of a square base made of 02 mm wire, and a mesh made of 01 mm wire, in the nodes of which pointed needles of 00.3 mm wire are soldered. From the corners to the center of the square there are four conductors soldered together. High voltage is supplied to this point, and the chandelier is suspended from the ceiling through the insulator.
The thyristor high-voltage converter consists of a step-down power transformer T1 (see diagram), a rectifier on VD1, a storage capacitor C1, a high-voltage transformer T2 and a thyristor-ill winding control unit T1, R2, VD2.
The converter works as follows. The current of winding 11 of transformer T1 in the first half-cycle charges storage capacitor C1 through diode VD1 and winding I T2. Diode VD2 is locked at this time, and thyristor VS1 is closed. In the second half-cycle, the thyristor opens* through diode VD2. VD1 is locked for the second half-cycle, so a short circuit through the thyristor is excluded. At this time, capacitor C1 begins to discharge through the thyristor and winding I of transformer T2. A high voltage is induced in winding 11 T2, which is supplied to the chandelier through a rectifier and a high-voltage PV wire.
Instead of the KU201L thyristor, you can use the KU202N. The use of triacs (for example, KU208) is unacceptable. T1 - any small-sized transformer from a tube radio (wind it yourself - on a Ш19 core, set thickness 30 mm: I winding -2120 turns PEL 0.2; 11 winding -2120 turns PEL 0.2; 111 winding -66 turns PEL 0.2 ). T2 - high-voltage coil from the electronic ignition unit of the chainsaw<Урал>or magneto. Can be made from a core and a high-voltage coil from a TV type CNT-35 (<Рекорд-66>, <Рассвет>). Wind the primary winding yourself with PEL 0.51 wire in the amount of 200 turns.
Instead of a high-voltage column VT-18/0.2, you can use 5GE600AF. Insulate high-voltage wires only with PVC tape. Before turning on the converter for the first time, connect a 220 V lamp in the gap at point A. If after switching on the lamp lights up, swap the terminals of winding III T1. If after this a high voltage appears, but the lamp continues to glow at least slightly, increase the resistance of resistor R2.
There should be no odors when the air ionizer is operating - this is a sign of the appearance of harmful gases that occur when high voltage leaks onto the housing or nearby parts.
Precautionary measures. When setting up and operating the converter, electrical safety must be observed. The high voltage current is limited to 2 µA, that is, thousands of times less than the maximum permissible, but this does not mean that you can touch the chandelier with impunity without receiving a strong prick from the discharge spark.
The operation of the converter can be judged by a slight crackling sound around the chandelier. The duration of the daily session is about 30 minutes. > In rooms with insufficient ventilation, turn on periodically throughout the day.

The power supply described above has good filtering properties; the transistor suppresses noise, ripple, and AC background. However, it is imperfect and unstable. For example, you set the output voltage to 5 volts. Your network voltage has increased, the voltage at the output of the diode bridge and capacitor C1 immediately jumps, naturally the voltage at resistor R1 increases, it divides it differently, the increased voltage is supplied to the base of transistor VT 1, and naturally an increased voltage appears at the output. When the network voltage decreases, the same thing happens in the direction of decreasing the output voltage. To prevent this from happening, parametric voltage stabilizers using zener diodes with an amplifying transistor are used. Let's consider several power supplies (voltage stabilizers) with a step-down input transformer.
They have several disadvantages:
1. Reduced efficiency
2. High power dissipation
3. Weight, determined naturally by the overall dimensions of the transformer.
But there are also advantages:
1. Complete galvanic isolation from the supply network, in contrast to pulse ones with a transformerless input.
This article discusses the assembly DIY Chizhevsky chandelier, which produces negatively charged air ions, it is also called an air ionizer.
A large number of measurements indicate that in one cubic centimeter of forest air there are from 600 to 1400, and sometimes up to 14,000 negatively charged air ions. The air will be more useful if there are a large number of these air ions. Unfortunately, in city apartments their content drops to 25 per cubic centimeter, which can result in significant fatigue and tiredness.
You can raise the level of air ions in the air of city apartments using a special device - the Chizhevsky ionizer. In the 20s of the last century, Professor Chizhevsky A.L. created the first such installation.
DIY Chizhevsky chandelier
This article will discuss a simple ionizer design that can be assembled with your own hands at home.
Chizhevsky chandelier consists of two parts - the chandelier itself and the high voltage converter circuit.
Chizhevsky's chandelier is an aluminum hoop with a diameter of up to 1 meter. Serviced copper wires with a diameter of up to 1 mm and with a pitch of 35 - 45 mm are attached to it, mutually perpendicular. The resulting mesh should sag at a distance of 60 – 90 mm. At the intersection of the wires, metal needles up to 40 mm long are soldered.
It is desirable that they be as sharp as possible, since the efficiency of the entire structure depends on this. It is necessary to attach three copper wires with a diameter of up to 1 mm to the hoop at an equal distance (every 120 degrees), which are soldered together at the other ends above the hoop. The high voltage generator itself is then connected to this point.
For effective operation of the Chizhevsky chandelier, a high-voltage voltage of at least 25 kV is required. For a room of approximately 50 sq. m requires about 30 kV to 40 kV. This can be achieved by adding to ionizer circuit the required number of multiplier stages. Below is a simple electrical circuit diagram of a high voltage generator for an ionizer, which has been tested for almost thirty-five years and has proven its effectiveness.
Description of the operation of an air ionizer for a Chizhevsky chandelier
At the moment of the positive half-cycle of the power supply, the capacitor C1 is charged through the chain of elements R1, VD1 and the winding of the transformer Tr1. Thyristor VS1 is locked at this moment. When a negative half-cycle arrives, diodes VD1, VD2 are in a locked state. A voltage drop is created at the thyristor cathode relative to the control electrode. An electric current appears in the electrical circuit of the thyristor control electrode and it opens. After this, capacitor C1 is discharged through the primary winding of transformer T1.
A high potential pulse appears in the secondary winding of the transformer and this is repeated every period. Electrical pulses of increased voltage pass through a rectifier assembled on diodes VD3...VD6 according to a voltage multiplier circuit. The rectified voltage from the output of this rectifier goes through the current-limiting resistance R3 to the chandelier.
Details and design of a homemade air ionizer
Transformer Tr1 - ignition coil B2B (6 V) from a motorcycle, but can also be used from a car. Resistor R1 can be assembled from three with a power of 2 W and a resistance of 3 kOhm, and resistor R3 from three or four for a total resistance of 10-20 MOhm.
Diodes VD3-VD6 high-voltage type KTs201G-E. Paper capacitor C1 is at least 250 V, C2-C5 are POV type capacitors for a voltage of at least 10 kV, and C2 is at least 15 kV. Thyristor VS1 KU202 K-N, KU201K. Any diodes VD1 and VD2 not lower than 400 V.
The ionizer parts must be installed in a housing of suitable dimensions so that there is a large distance between the terminals of the capacitors and high-voltage diodes. To prevent the occurrence of corona discharges in the ionizer, it is advisable to cover these terminals with molten paraffin after installation. When installed correctly, the Chizhevsky chandelier begins to work immediately.
There should be no odors during operation of the ionizer. The smell indicates the presence of harmful gases (nitrogen oxides or ozone). They should not appear near a properly working chandelier. If they appear, you need to inspect the device again and connect the ionizer to the Chizhevsky chandelier.
The output voltage can be changed by selecting resistance R1 or capacitance C1. You can verify the functionality of the ionizer by placing (carefully!) a piece of cotton wool near a working Chizhevsky chandelier. At about a distance of 50 mm it will be attracted to the chandelier. Also, at a distance of about 10 cm, a light breeze of air ions is felt.
Attention! Since the circuit elements are energized, electrical safety measures should be observed when setting up the ionizer.
Air is the most important natural resource that humans cannot do without. The state of health largely depends on its quality. To boost immunity and improve well-being, doctors advise spending more time in the “fresh air.” However, increased pollution in cities deprives people of this opportunity. Everyone gets out of this situation in their own way. One of the methods to solve the problem is to use a Chizhevsky chandelier in the apartment. What this device is, whether it brings benefit or harm to the body and how to do it yourself - these are the topics that will be covered in this article.
What is a Chizhevsky chandelier?
The Chizhevsky chandelier is a device designed to saturate the air with high polarity ions. The unit received its name from the name of the famous scientist. He was the first to develop an electroeffluent device, on the basis of which the chandelier itself was created. It is the world's first air ionizer. Thanks to Chizhevsky’s chandelier, a person can get that same “fresh air” in his apartment that benefits the body.
The benefits and harms of Chizhevsky's chandelier
There is no consensus among scientists about whether the device is beneficial or harmful to the body. On the one hand, experts do not deny the fact that the device purifies the air, neutralizing the effect of harmful bacteria. On the other hand, the oversaturation of oxygen with negatively charged ions in itself can cause harm to human health. Only the balance of all air elements will avoid such a result. However, achieving balance at home is almost impossible. Therefore, scientists were divided into supporters and opponents of the device.
Advantages
Experts who are positively disposed towards the unit have found that Chizhevsky’s chandelier benefits the body:
- accelerates the process of restoration of soft tissues after mechanical damage, which includes scratches, burns, cuts, etc.;
- improves the body’s condition in case of infectious pathologies, promoting a speedy recovery;
- increases endurance and performance;
- prevents the occurrence of cardiovascular pathologies, in particular heart attack and stroke;
- normalizes metabolic processes occurring in cells;
- increases the body's defenses;
- reduces the likelihood of the spread of infectious pathologies;
- generally improves a person’s well-being, relieving chronic fatigue and weakness;
- has a positive effect on the nervous system.
Experts advise using the Chizhevsky chandelier to purify the air for people suffering from pathologies of the respiratory system - bronchitis, asthma, whooping cough and tuberculosis (only at the initial stage of development). The use of the device is also relevant for allergies, high blood pressure and unstable emotional background.
Modern scientists have been able to establish that Chizhevsky’s chandelier has a positive effect not only on people, but also on animals, so the device can also be used in those homes where beloved pets live.
Flaws
Some scientists have concluded that using the device can cause harm to the body:
- worsens the functioning of the respiratory system and against this background wheezing and other pathologies occur;
- disrupts heart function;
- provokes frequent headaches;
- creates additional stress on the body, which makes overall health worse.
Description of the Chizhevsky chandelier
The Chizhevsky chandelier, the benefits and harms of which are still controversial among scientists, is an indoor device of a tabletop or pendant type. The unit runs on electricity. After turning it on, negatively charged ions begin to be produced, which results in air disinfection.
What does Chizhevsky's chandelier look like?
The device is a plastic cylindrical body, on top of which a wire spherical metal frame is fixed. It is the working part of the device. It is he who produces air ions. The device is equipped with a cord and plug that connects to the network. The device can be installed on any flat surface or hung on the wall.
Principle of operation
The operating principle of the device is to supply high voltage to the electrode. Due to this, negatively charged ions begin to be released into the environment. When a person inhales air saturated with these particles, they penetrate into the body and give their charge to red blood cells. These formed cells, in turn, deliver ions to all human organs and systems, which improves the metabolic processes occurring in the cells.
Instructions for use
To avoid negative consequences from the operation of the device, you must follow the instructions for its use. Before turning on the unit, the room needs to be well ventilated.
The duration of the first use should not exceed half an hour. Gradually the time can be increased. After several sessions, the operating time of the chandelier should be 3-4 hours a day.
When the chandelier is working, all windows and vents must be tightly closed, otherwise air masses may carry away the generated ions. If after the first sessions you experience any discomfort such as headaches or dizziness, there is no need to worry. These conditions are not a side reaction of the body or a manifestation of pathology. They often occur in metropolitan residents after prolonged exposure to the so-called fresh air. To avoid recurrence, it is recommended to shorten the next session. When dizziness and headaches do not bother you, you can increase the duration of operation of the device, bringing it to the desired value.
Contraindications
Skeptical specialists have established contraindications for using the device:
- exhaustion of the body;
- increased blood pressure in the kidneys;
- oncological pathologies;
- bronchial asthma and similar pathological conditions;
- pulmonary tuberculosis in late stages of development;
- pathologies of the cardiovascular system, which include heart failure, atherosclerosis and vascular spasms;
- ozena.
To date, no reasonable evidence has been provided that the device cannot be used for these conditions, but a number of experts argue that contraindications are relevant.
How to make a Chizhevsky chandelier yourself?
Despite the fact that the device is not a scarce commodity and acquiring it in our time is not difficult, ordinary people are interested in the question of how to make a Chizhevsky chandelier on their own. To manufacture the unit, you will need a metal rim, the diameter of which should be 1 meter. Bare copper wires with a diameter of 1 mm are stretched onto it. They are fixed at a distance of 4 cm from each other. The wires should form a hemisphere with a slight sag at the bottom. Needles with a length of 5 cm and a diameter of 0.5 mm are soldered into the sides on four sides. It is important to ensure high-quality sharpening of such elements. This prevents the formation of ozone, which can cause severe harm to the body. For this reason, experts advise purchasing a professionally produced Chizhevsky chandelier rather than making the device yourself. Three copper wires with a diameter of 1 mm should also be soldered to the rim. At one end they are fixed on the made device, and the other ends are soldered together above it. The final stage is the creation and connection of the power supply, from which all the operation of the unit will be carried out.
To make a generator you will need:
- fuse;
- diode;
- voltage divider;
- a pair of dinistres;
- output to resistor winding;
- diode bridge;
- capacitor;
- timing chain.
A generator is assembled from such elements and fixed to the device. After this, you can start using it.
To check the functionality of the unit, you need to turn on the device and bring your hand to the needles at a distance of 10-15 cm. If you feel cold, it means the unit is functioning. There is another way to check. You need to take a small piece of cotton wool and bring it to the device at a distance of half a meter. If the fiber is attracted to the unit, then the chandelier is functioning normally.
Manufacturers of Chizhevsky chandeliers
The Chizhevsky chandelier is produced by several manufacturers:
- EcoUnit - makes Chizhevsky chandeliers with a ceramic body. Thanks to its stylish design, the device will fit into any interior. Disadvantage: if not handled carelessly, it can break.

- Hippocrates - devices from this manufacturer are equipped with an air purification filter and ultraviolet disinfection. The units operate in two modes. They are easy to use and do not consume much electricity. Easily disassembled to change filters.
Where to buy a Chizhevsky chandelier?
You can buy a Chizhevsky chandelier in the online store. There is a large selection of units from various manufacturers available here. Prices range from 1,500 to 6,000 rubles. In specialized stores you can also purchase air ionizers made based on Chizhevsky’s developments. Cost from 1000 to 10000 rubles.
Chizhevsky's chandelier is a device thanks to which “fresh air” like in the forest can be obtained even in a city apartment. Despite the fact that scientists have not been able to prove that the device causes harm to the body, it is recommended to use it for various pathologies only after the approval of a doctor.
Surely everyone has heard about such an invention as the “Chizhevsky Chandelier”. This device is capable of charging the air with negative ions, which has a very beneficial effect on health. According to some, such a device can cure a number of diseases. In nature, air with similar qualities can only be found in the mountains, but now it is possible to create mountain air at home.
The Chizhevsky chandelier was invented in 1927, and to this day it is actively used in medicine, crop production, livestock farming, and so on. Today this miracle of technology can be bought, but not all devices are able to work correctly. For example, in a purchased device, the voltage at the electrode is rarely more than 25 kV, which means that such ionized air does not affect health at all. And if the ionizer produces the smell of ozone or nitrogen oxides during operation, then this is all harmful to health. Let's look at a few simple diagrams with which you can assemble an air ionizer with your own hands.
Materials and tools:
- soldering iron with solder;
- high voltage transformer;
- transistors;
- zener diodes;
- diode bridges;
- resistors;
- capacitors;
- and other radioelements.
The complete list of materials depends on the specific homemade product chosen.
Ionizer manufacturing process:
The safest air ionizer
The safest version of the air ionizer was presented on a popular electronics website.
First of all, the advantage of the device is that it does not contain external elements that carry high voltage, and therefore the likelihood of receiving an electric shock when touched is reduced.
Another proposed circuit does not create the same level of radio interference and produces less static voltage, which can render surrounding equipment unusable.
And finally, industrial ionizers often attract dust very strongly; here they also tried to eliminate this drawback.
Ionizer circuit from RADIOSKOT.RU
The basis for the ionizer is a multivibrator built on transistors VT1 and VT2. The multivirbrator frequency is changed using trimming resistor R7 in the range from 30 to 60 kHz. From the multivibrator, pulses are sent to a voltage converter; it was built on two transistors VT3, VT4, as well as transformer T1. When the frequency on the converter changes, the output voltage at the converter output changes. If you decrease the frequency, the output voltage will increase.
Next, the high voltage (about 2.5 kV) from the secondary winding of transformer T1 goes to the input of the multiplier; it is assembled on capacitors C8-C13 and diodes VD5-VD10. Well, then the voltage is sent directly to the chandelier itself; it is made of a multi-core copper cable, the cores of which are branched like an umbrella at right angles. One terminal of the secondary winding of transformer T1 is connected to the body (minus) of the device. The distance between the electrodes is selected individually.
Protection
To prevent the system from creating too large a potential difference between the electrodes and other structural elements, resistors R8-R10 are used. To prevent the secondary winding of the transformer from being punctured, the system is equipped with an SG1 arrester.
Nutrition
The power circuit is based on capacitive reactance. It consists of a zener diode VD2, capacitors C1, C2, a diode bridge VD1 and resistor R2.
Case and fan
To make the device safe, it is placed in a case from a computer power supply. To ensure the circulation of ionized air, a computer cooler is used, which is located in its original place in the power supply. The fan operates from a 12V power source and a separate circuit is also provided for it.
As for the transistor, it must be powerful; IRF740 or IRF840 are well suited for these purposes. As for the transformer, the one used in kinescopes for horizontal scanning is used here. On the free side of the core you need to wind ten turns of copper wire with a diameter of one millimeter. The secondary winding of the liner is used.
High voltage is supplied from the secondary winding to the rectifier and then charges the capacitor. You can use KTs106G or KTs123 as a diode.
A couple more air ionizer circuits
The website posted a diagram for creating a classic air ionizer, that is, in the form of a chandelier. The main ring is made of bare copper wire with a diameter of 4.5 mm. Next, a thinner copper wire with a diameter of 0.7-1 mm is pulled perpendicularly onto this ring.
You can also use a metal gymnastic hoop to create a ring.
