DIY kacher

Beginner radio amateurs show a very great interest in high-voltage technology. Today we will touch on the topic of one such device, well known to everyone - the kacher.
The kacher is designed to produce high-frequency voltage and can serve as the basis for interesting amateur radio devices. With a ready-made kacher you can carry out a series educational experiences, For example ion engine, the glow of gas lamps away from the device and the transmission of energy with one wire. Below is a look at the Brovin quality option.

Device diagram:

Primary winding consists of 5 turns of copper wire with a diameter of 4.5 mm, winding diameter 10 cm, wound in the form of a spiral. Secondary winding has 1300 turns, wire 0.12 mm. The winding is wound on a PVC pipe, the height in my case is 15.7 cm.

Transistor KT808AM needs to be installed on a heat sink, replacement is also possible, since the transistor is not critical, you can use the well-known ones - KT805, KT819, to obtain more high power KT827.

The circuit operates in a wide range of supply voltages, from 2 to 30 Volts, typical - 12 Volts.

You can also use direct conduction transistors in the circuit, only in this case you will need to change the polarity of the power supply.

What to do if the scheme does not work?
First, check the serviceability of the transistor; if it is working, then swap the leads of the primary coil.
If the kacher is working, but the current on the high-voltage winding is very weak, then lower the R2 rating to 10k, it is advisable to replace this resistor with a tuning resistor for more accurate tuning.

The idea to modify the Brovin quality camera circuit, well known to many, came to me after some of my friends could not start this camera due to the lack of a power source with a voltage of 12 Volts or higher, which is indicated on standard scheme. To get around this obstacle, I decided to combine a quality generator circuit and a blocking generator, which made it possible to lower the supply voltage to 5-6 Volts (although it can be raised to 15 Volts). The Brovin quality diagram is shown below.

List of required parts for the circuit:

Any ferrite ring (height 0.7 cm, outer diameter 1.5-2 cm, inner diameter 0.5-0.7 cm; dimensions are not critical);
- 2 resistors 1 kOhm 0.5 W;
trimming resistor 220 Ohm 0.25 W;
- 2 transistors KT805;
- 2 radiators for transistors
- 1 rectifier diode 1 A;
- capacitor 10000 uF 50 V;
- winding wire 0.25 mm;
- single-wire copper wire 1.5 sq. mm (for primary coil);
- wire 0.5 sq. mm single-core stranded (for connecting all parts together);
- a piece of plastic (not metal-plastic!) pipe 30 cm from a regular water supply (0.5") and a board for making a stand.

The primary coil of the kacher is wound with a single-wire wire (a copper core from a VVG cable, for example) on any round mandrel with a diameter of 5-7 cm - 4 turns, the mandrel is removed after making the coil. The height of the primary should be 10-15 cm, i.e. the primary winding is then stretched to required length. The secondary is wound 800-1400 turns in one layer with a thin wire on a pipe. Next, everything is assembled according to the diagram. Structurally, the primary winding should be around the bottom of the secondary.

Setting up the quality control circuit is extremely simple and is done by adjusting R1. If the circuit does not work, swap the ends of the primary. It is imperative to attach radiators to the transistors, since they heat up significantly. The operation is checked by holding it close to the coil. energy saving lamp. Good luck with your experiments! Author: Scheme Here.

In my work I want to show how you can use electrical appliances that are not connected to the network, and I will prove that this can be done at home without much expense.

Chapter I. Theoretical part

1.1. The device and principle of operation of the Brovin Kacher

The Brovin Kacher was invented in 1987 by Soviet radio engineer Vladimir Ilyich Brovin as an element of an electromagnetic compass. Engineer Brovin V.I. Higher education – graduated from the Moscow Institute of Electronic Technology in 1972. In 1987, he discovered inconsistencies with generally accepted knowledge in the work electronic circuit the compass he created and began to study them. He made many inventions at home. One of them is Kacher Brovina.

Let's take a closer look at what kind of device this is. Brovin's kacher is a type of generator assembled on a single transistor and operating, according to the inventor, in abnormal mode. The device exhibits mysterious properties that date back to the research of Nikola Tesla. They don't fit into any of the modern theories electromagnetism. Apparently, Brovin's kacher is a kind of semiconductor spark gap in which the discharge electric current passes through the crystalline base of the transistor, bypassing the stage of formation of an electric arc (plasma). The most interesting thing about the operation of the device is that after a breakdown, the transistor crystal is completely restored. This is explained by the fact that the operation of the device is based on reversible avalanche breakdown, in contrast to thermal breakdown, which is irreversible for a semiconductor. However, only indirect statements are given as evidence of this mode of operation of the transistor. No one, except the inventor himself, has studied the operation of the transistor in the described device in detail. So these are just assumptions by Brovin himself. So, for example, to confirm the “black” mode of operation of the device, the inventor cites the following fact: they say, no matter what polarity the oscilloscope is connected to the device, the polarity of the pulses shown by it will always be positive.

Maybe kacher is a type of blocking generator? There is also such a version. After all electrical diagram The device strongly resembles an electrical pulse generator. Nevertheless, the author of the invention emphasizes that his device has a non-obvious difference from the proposed circuits. It provides an alternative explanation for the occurrence of physical processes inside the transistor. In a blocking oscillator, the semiconductor periodically opens as a result of the flow of electric current through the coil feedback base chain. In quality, the transistor must be permanently closed in a so-called non-obvious way (since the creation electromotive force in the feedback coil connected to the base circuit of the semiconductor is still capable of opening it). In this case, the current formed by the accumulation electric charges in the base zone for further discharge, at the moment the threshold voltage value is exceeded, it creates an avalanche breakdown. However, the transistors used by Brovin are not designed to operate in avalanche mode. A special series of semiconductors has been designed for this purpose. According to the inventor, you can use not only bipolar transistors, but also field and radio tubes, despite the fact that they have fundamentally different physics of operation. This forces us to focus not on research on the transistor itself in the quality, but on the specific pulse mode of operation of the entire circuit. In fact, Nikola Tesla was engaged in these studies.

Kacher Brovina is an original version of an electromagnetic oscillation generator. It can be assembled using various active radioelements. Currently, when assembling it, field-effect or bipolar transistors are used, less often radio tubes (triodes and pentodes). Kacher is a reactivity pump, as the author of the invention, Vladimir Ilyich Brovin, himself deciphered this abbreviation. The Brovin Kacher is powered by a modified 12 V, 2 A network adapter and consumes 20 W. It converts an electrical signal into a 1 MHz field with an efficiency of 90%. One of the parts of this device is a plastic pipe 80x200 mm. The primary and secondary windings of the resonator are wound on it. The entire electronic part of the device is located in the middle of this pipe. This circuit is completely stable, it can work for hundreds of hours without interruption. The Brovin Kacher with self-powering is interesting in that it is capable of lighting unconnected neon lamps at a distance of up to 70 cm.

1.2. Areas of use

Wide practical application of new devices and products operating on the basis of this new physical phenomenon will make it possible to obtain a very significant economic, scientific and technical effect in various fields and areas human activity.

Let's consider the areas of application of this device:

1. New relays and magnetic starters based on the widespread use of kacher technology:

• can lead to a reduction in energy costs and an increase in production efficiency in general, which together will provide a very significant economic effect in the country’s economy;

2. Devices that illuminate fluorescent lamps (lamps daylight) not from 220 V, as now, but using KACHER technology products, from a supply voltage of 5 to 10 V:

• this will significantly reduce the level of fire and explosion hazards

3. Devices that provide the possibility of not serial (currently used), but parallel connection individual elements solar panels:

• will significantly increase the reliability, durability and efficiency of their operation, as well as obtain a significant economic effect from their use;

4. Devices for inductive transmission of control information and energy between different traffic lights located on different sides of the intersection and included in one traffic light object (without the use of electrical wires currently used for this, with large labor costs for their installation):

• will save energy and costs.

1.3. Negative impact

Despite the positive aspects of using this device, one cannot fail to note its negative impact. Carrying out this practical work, I noticed that due to the strong electromagnetic field created near the kacher, fail Cell Phones, camera, tablet. And here I thought that in addition to the positive aspects, this device has a negative effect, including on the human body. After reading the literature on this issue, I found out that a strong electromagnetic field has Negative influence on nervous system person. Staying near a working device for a long time causes a headache, and upon close contact, a slight aching pain in the muscles of the arms. In addition, as it turned out, the kacher can emit ozone, which we can feel by the corresponding smell.

Also, do not touch the discharges with your hands; due to the high frequency, a small burn may remain on the skin. Thus, we can conclude that when working with this device it is necessary to follow the safety rules:

1. Do not try to touch the discharges with your hands. The pain, if there is any, will not be severe, but you are guaranteed a burn.
2. Keep pets away from the device.
3. Do not bring it near the device Cell phones and other electronics.
4. You should not stay near the switched on device for a long time.

Chapter II. Practical part

2.1. Assembling the Brovin quality camera installation

Let's consider the stages of assembling this device at home.

Basic elements of Kacher:

1. inductor (secondary winding);
2. inductor (primary winding);
3. pay.
4. frame

The diagram that I followed during assembly is as follows:

Installation details:

1. Polyvinyl chloride (PVC) pipe with a diameter of at least 25 mm and a length of 30 cm (the glow range of the light bulbs will depend on this). I used a pipe with a diameter of about 55 mm.
2. To make the secondary winding of the kacher, I used copper wire coated with a double layer of varnish and 0.20 mm in diameter. It should be wound on the pipe, at least 1500 turns. (My copy of the kacher has about 2000 turns wound on it.) Every few centimeters I applied glue to fresh turns, otherwise the winding might get lost and tangled.
3. To make the primary winding, I needed a copper wire with a diameter of 0.5 cm, which must be wound around the secondary coil. It is necessary to make about 4 turns. We wind all the windings in one direction! We install and secure the pipe with the winding on plywood or a board, stretch the primary winding by 1/3 of the secondary. The windings must not touch! Then we fuse a metal wire the size of a sewing needle into the pipe from above and solder the end of the winding to it. Next, we screw the radiator for the transistor to the platform next to the coils, coat the base with heat-conducting paste and screw the transistor to the radiator with a metal socket.

To make the board I needed the following radio components:

1. throttle,
2. non-polar capacitor (1000 v 3000 μ F),
3. 2 resistors (2.2 kOhm and 150 Ohm),
4. NPN transistor, the more powerful the better (they can be found in a regular PC power supply or on the board of old tube TVs).

Everything is mounted as shown in the diagram (Fig. 1). Solder the power wires.

This device must be connected to a power supply with a voltage from 12 to 38 v, which I also designed myself (Fig. 3)

The quality check is carried out by presenting fluorescent lamps glasses to the secondary winding, if connected correctly it will light up. When the secondary winding is touched by a metal object, there will be a discharge between them. If the kacher does not work, then you need to check whether the circuit is assembled correctly or try changing the ends of the primary winding.

2.2. Effects observed during the operation of the Brovin quality camera

Let's consider the effects observed during the work of Kacher Brovin, which I constructed at home.

1. We bring a fluorescent lamp to the secondary winding, we see that it lights up. (Fig. 4) If you bring a gas-discharge lamp to the kacher, it also begins to glow. (Fig. 5) The same effect is observed with other similar lamps. Also in a regular incandescent lamp you can see the so-called glow discharge. (Fig. 6)

1. While working, the kacher creates beautiful effects related to education various types gas discharges are a set of processes that occur when an electric current flows through a substance in a gaseous state. Brovin's quality ranks:

• Streamer (from English Streamer) - dimly glowing thin branched channels that contain ionized gas atoms and free electrons split off from them. Streamer - visible ionization of air (glow of ions) created by an explosive - Kacher field. (Fig. 7)

• Arc discharge occurs in many cases. For example, with sufficient transformer power, if a grounded object is brought close to its terminal, an arc may light up between it and the terminal. Sometimes you need to directly touch the terminal with an object and then stretch the arc, moving the object to a greater distance. (Fig. 8)

Conclusion

Kacher Brovina – original version generator of electromagnetic oscillations. In my work, I proved that it is possible to make a working model of a kacher at home, and also considered the possibilities of its practical application. I would like to note that my work in this direction is not finished. In the future, I want to make a Brovin kacher with audio modulation. To do this, you need to complicate the circuit a little by adding two resistors and a transistor. (Fig. 9) Thus, we will be able to play music through the power supply circuit of the camera. In practice it looks beautiful and interesting.

As a result of the research carried out in this work, we can conclude that the Brovin Kacher is a simple device to manufacture and configure. With which you can demonstrate many beautiful and impressive experiments. During the operation of the coil, we observed two types of discharges.

Analyzing all of the above, we can say that Kacher Brovina can be successfully used in alternative energy, for example, in devices for generating free electricity using permanent magnets.

In conclusion, it is necessary to emphasize the following: the creation of new technologies based on the described physical phenomenon can give Russia very significant advantages over other countries. Since, having carried out in the near future all the necessary studies of this physical phenomenon and developed a wide range of new devices and products operating on its basis and intended for wide practical use in various areas and spheres of human activity, Russia can make a new qualitative leap in its further technological development. The introduction of Russian know-how will radically change the entire infrastructure of the energy sector and society as a whole - when it is unexpectedly discovered and experimentally confirmed new way obtaining energy.

Kacher is a device that generates high voltage(5000-20000 volts) high frequency. Don't be afraid - you won't be electrocuted. This is not the same current as in a socket - it has a high frequency (up to 250 kHz), and in our socket it is 50 Hz. At high frequency, current flows across the surface of your body.
The most simple circuit is shown in Figure 1. In order to assemble this circuit, you will need a minimum of parts that can be found in old TVs:

1. 2 resistors
2. 1 p-n-p junction transistor (it must be powerful and high-frequency, for example
kt805. See the catalogue)
3. 1 Capacitor
4. Copper wire 0.15 - 0.25 mm (can be purchased at a radio store or by unwinding any power transformer)

We buy resistors or unscrew them from any radio boards. You can also remove the capacitor from the boards. The transistor can also be unscrewed from the board - they are usually mounted on radiators. Please ensure that the transistor has p-n-p junction, if it will be n-p-n junction– you need to change the collector and emitter connections. What can be said about the radiator, it should be large, and if you do not have a large radiator, then install a cooler on a small radiator. We take copper wire from any transformer.

Now let's start assembling:
We take a cardboard tube and wind the secondary winding turn to turn with wire (0.15-0.25), periodically filling it with varnish. This is the most painstaking work. The more turns, the better the end result. Now around the secondary winding we make 3-4 turns with a thicker wire (wire, plate) whose thickness (width) should be 1-4 mm. Next, we connect these 2 windings to the circuit and connect this device to the network. And what do we see? When you bring a fluorescent lamp to this device, it lights up without wires... We can conduct electricity through the body without harming any organ, to do this, it is enough to bring your hand to the secondary winding and with the other hand grab tightly to one of the contacts of the fluorescent lamp...

Note: If the device does not work, then turn over the primary winding, i.e. magnetic fields windings must match. If you wind one winding clockwise, then the second one should be wound in the same way.

WHY doesn’t “Brovin’s Kacher” work?

Why might such a simple generator not work and how to set it up? For reliable operation of the generator, a number of simple requirements for the circuit elements must be met.

1. The coil must be long and multi-turn. The winding should be tight. A short, low-turn coil with sparsely wound turns resonates excessively high frequencies. The same result is caused by gaps in continuous winding, which are obtained, for example, when soldering a wire broken during winding and the presence of a large gap between adjacent turns in this place.

2. The transistor must be high enough to generate at the frequency of the oscillating circuit. Commonly used transistors KT805 with in different letters have a cutoff frequency of about 20 MHz, KT903 - 120 MHz, KT902 - 35 MHz, KT819 - 3 MHz. With short coils, not all transistors can generate at the required frequency. Good results should provide high-frequency (but expensive) KT921A transistors with a cutoff frequency of up to 300 MHz.

3. It is necessary to select the correct DC mode of the transistor. The current through a transistor depends very strongly and nonlinearly on the voltage between the base and emitter of the transistor. When this voltage is less than 0.5 V, the transistor does not conduct current and does not amplify or generate current. With a value of 0.7-1.0 V, the current can change sharply from very small value up to 3-5 amperes, the transistor amplifies and generates. At a voltage of 1.5 V, the maximum possible current flows through the transistor; the transistor no longer amplifies or generates.

You can set the desired current of 0.5-1.5 amperes using resistors. To do this, with a 12-15-volt power supply, the easiest way is to solder the lower resistor with a constant value of 150-300 Ohms, and instead of the upper one, solder a chain of a 1 kOhm resistor and a 10 kOhm variable resistor connected in series with it. One of the extreme and middle (movable) terminals are used. In the initial position, the distance between the moving and outer terminals (and, therefore, the resistance between them) should be maximum. You need to connect an ammeter of 2-10 amperes to the gap in one of the power wires and, by turning the resistor knob, set the current to 0.5-1.5 amperes. If there is no such ammeter, then you need to monitor the appearance of generation using neon or fluorescent lamps located close to the coil. If there is no generation, then you need to swap the leads of the primary winding and repeat the setup.

The current through the transistor strongly depends on its heating during generator operation. During prolonged operation, the transistor may become uncontrollable due to overheating and fail (burn out). To reduce this effect, you can solder a 1 Ohm resistor with a power of 2 W into the emitter circuit.

4. For reliable generation, independent of the parameters of the power source, the circuit between plus and minus must have a capacitive decoupling, preferably two capacitors connected in parallel: one electrolytic with a capacity of approximately 1000 μF, which can withstand the voltage of the power source with a reserve, the other paper or ceramic with a capacity of 0. 1-0.5 µF with the same operating voltage requirements. Electrolytic capacitor Usually there is an internal power supply, so it can be omitted.
