Classic kacher (Cacharel reactivity) consists of a control element (UE) and a coil with two windings . Circuitry its excitation is similar to the oscillator, which is excited by the positive feedback (PIC), through these inductances. But kachery mode differs fundamentally. This confirms at least the fact that the two existing windings you can post at any desired distance from each other, and Kutcher, in contrast to the oscillator, will still self-oscillate. The explanation for this phenomenon pretty much from the unusual properties of semiconductors and avalanche modes of their work [2,3], to the so-called "nods" — the mechanical movement of the magnetic moments of atoms occurring under the action of magnetic fields in the paramagnetic .
According to the author, the self-excitation of such schemes, and kichernyi mode of operation occurs due to the properties of the coil conductor. In moments of fast differential voltage UE, in a conductor creates conditions for the manifestation of the dynamic skin effect in the form of voltage surges and current, by the way, is very similar to NMR (nuclear magnetic resonance). Such emissions are quite high frequency and is able to use the parasitic capacitance in the UE to create the conditions for generation. Thus, the classical PIC via associated inductance, there is no longer mandatory. It is this oscillator are essentially a managed kacher, we will present in this work.

Difference of this oscillator is half-wave mode on the output coil, when the electric field intensity is maximum at its center and decreases at the edges (Fig. 1a). The second difference is the design of the output coil, which half-wave vibrator, and the inductor is combined (Fig. 1b, 1c), and a feedback circuit formed by the parasitic capacitance of the output transistor (Fig. 1d). In addition to this autogeneration unusual here is the fact that the primary winding L1.1, together with capacitor C1 form a series resonant circuit tuned to the LC resonance, while the secondary winding operates at a frequency of wave resonance. The correct combination of these two modes allows to obtain unusual and non-classical effects, and the kacher provides seekers of free energy another tool for research. In addition, if necessary, it can easily be controlled by external low frequency generator.
A self-sustaining loop
It is necessary to consider the circuit L1C1 in more detail. From electrodynamics we know that a half-wave vibrator at the ends there is a low voltage, but high current, and at its centre — high voltage. This vibrator here represented by coil L1.2. Much the same can be said of the series resonant circuit, the current which will be the same at its ends, and the voltage in the middle, at the point of connection of capacitor C1 and inductance L1.1, will be high. Combining these two effects, we get the circuit design of our circuit (Fig. 1b, 1c). Because at the ends (a and b) there is a minimum voltage, but large enough current, as the UE can apply a relatively low voltage transistor (VT1) with a very small resistance of the open transition. This is a clear advantage of this katscher.
But the chain L1.1C1 and L1.2 can give the desired result only if they work together, as they support the oscillatory mode of each other. Therefore, the coil L1.1 here acts as the inductor, and L1.2 — as the secondary winding (Fig. 2). Ideally, once running in a loop momentum fluctuations there will be samomoderirovanie very long, and if we provide an external current source, it is — and grow. Yet the task is not ideal, therefore, to support oscillations, we apply the UE in the form of a field-effect transistor: VT1 in the figure (1d). This transistor must be driven by external generator, which should be supplied to him sufficiently short pulses, the length of which must be a multiple of or coincide with a resonant frequency of the whole circuit. Also do not forget that through its parasitic capacitance, with a positive control pulse, the transistor goes into kachery mode, thus greatly enhances this effect. For this reason, bipolar transistors don't work here, because their parasitic capacitance by orders of magnitude less than that of the field or composite igbt-transistors. As a result of experiments Lysanias that the UE is optimally suited IRF3205, which has the least resistance of open channel.
The list of schema elements:
Figure 2 shows a photo of an adjustable coil for our katscher. It allows you to move the inductor relative to the secondary winding and to find the optimum position. But in reality, the coil may be of any design, it is important only that the inducer had a few turns relative to the secondary winding and located closer to its edge. The gap between the primary and secondary windings also are not fundamental.
A generator generating control pulses to VT1, can be generally any. It is important only that the duration of the output pulses was a multiple, or coincide with the resonant frequency of the whole circuit. And this can be achieved settings. Suitable such generator, and output the key, it's already installed.
Setting the optimal mode
Kutcher will begin its work immediately and in any component values, but a more efficient power output will be obtained after finding the optimal mode.
First, it would be good to determine the frequency of half wave resonance coil L1.2, and then to find the capacitance of the capacitor C1 via the inductance of the inductor L1.1 and the received frequency. This should be done with the chains L1.2 and L1.1C1 separately, and then to select the duty cycle and frequency of the oscillator. If no such selection, then the schema is "as is", and then adjusting the duty cycle of the generator is selected the best mode of operation katscher, which can be controlled by the oscilloscope, the probe which must be placed near the coil. On his screen we need to get the correct sinusoidal oscillations which decay after decay of the control impulse. When placed next to a coil of the fluorescent lamp (the load), then the decay rate of the oscillations should increase (Fig. 3,4), and vibration damping to be nearly as should not (Fig. 5). Then you need to change the capacitance of the capacitor C1 and repeat the procedure again. To adjust the frequency of the LC resonance can be used ferrite rods, inserting them from the side of the inductor.
Next, are some waveforms for the coil in the photo (Fig. 2). It contains 1000 turns of wire 0.6 mm, wound on a plastic pipe 75 mm. Yellow curve shows the pulse generator, and the green electric field fluctuations near the coil. Thus there is the effect of ultra-low consumption katscher compared to power light bulbs.
