Kapanadze Cousin - DALLY FREE ENERGY

[TinselKoala]

@NickZ and others who may be interested:
Here's a photo of the main board of my TinselKoil 2, which seems to have circuitry very similar to some of those I've seen in this thread and the other Kap threads. I've annotated some parts of interest. This circuit took some time to develop and I blew a lot of transistors doing it, but in the form shown it's reliable and robust, as long as proper cooling is provided to the transistors.

It has a TL494 chip producing the clock pulses, with duty cycle and frequency control from the little blue trimpots. The output of this PWM chip is then split and inverted by the 2n7000 stage, producing 2 antiphase square waves. These are then fed to the PNP-NPN bipolar H-bridge for current amplification. The outputs from this bipolar bridge are fed to the primaries of 2 trifilar toroidal phase transformers. Their outputs then directly drive the gates of the corresponding high-current mosfets in the primary H-bridge. This bridge switches 170 VDC from the main DC supply from the mains, and is capacitively coupled to the resonator's primary coil consisting of a few turns (4, IIRC) of heavy wire around the base of the low-aspect-ratio secondary.
The primary bridge can be switched from full-bridge to half-bridge mode by the little toggle switch, and the whole thing can be put into autoresonating mode by letting a CMOS inverter/schmitt trigger chip with a little antenna detect the field of the resonator and make pulses to clock the 494 that way, instead of using the external RC network for fixed timing.

And then I've attached an image of a characteristic "psark" from this coil. It's about 15 cm long.

  According to Ismael, the compression of the surrounding ambient by the spike, draws in additional energy.
And, the shorting of this peek is done through resonance using a capacitor. The problem is that this high energy spike will kill the IGBT.  And it costed $200.000 to resolve this, by filtering.

  Tinsel:
   Ok, so there are some similarities.  And you should be able to help figure out what Akula is doing in his set up.
   It does seam as the working principals are the banging together of two different pulses, or maybe just one, and harvesting the additional energies that are created by that action, using resonance to control the shorting, at the right frequency.
I may not be saying correctly, but I think I'm getting the point.  NOW, the HOW to do it, is what we need, as always.

The diodes facing each other from Gate to Source on the mosfets are most probably not 1n4148, but rather are 12 or 15 volt Zeners. This is a common thing to do when using mosfets, to protect the gate from overvoltage spikes. It's sort of a gate voltage regulator. I can't think of any reason that one would use a small signal switching diode here, but it makes good sense to use Zeners.
The red wires from the yoke appear to go to the mosfet drains (middle pins) and the blue wires from the driver go to the sources (rightmost pin). The other diodes and cap on the mosfets: one is probably a Schottky diode to supplement the mosfet's body diode, between source and drain, to keep the mosfet cool.
The cap, other diode and resistor together I'm not so sure about.

Yes it zener diodes 12 volts let say. I use always zener diode, but only one betwen gate and source  to protect mosfet. Also 10-20 kiloom resistor. Akula use very much protections, zener diodes, varicaps (that seems like kapasitors), diodes, it very complex protection mosfets, but you can use only one zener diode and resistor, but resistor is more not for protection, for mee good work, but sometimes burn. If you have many many, then to save time better use one zener and one resistor, than try make didicult protection, I think.

Like kids... (don't take seriously) When this stuff will become as general knowledge the "pot" will be in everyone's house who wanted it.
I shared my knowledge, your turn to use it or ignore it.
