Kapanadze Cousin - DALLY FREE ENERGY

Maybe intended to 'sharpen' the gate pulse leading edge as sometimes used with bipolar transistor switching. Not needed with mosfets. Could these be IGBT's?

You can use bipoliar, but with bipolar can be problemms, for it need thour resistor let say 500 oom go to base and parallel resistor capasitor about 0,01 mikrofarad, then works better, but bipolar advantage, that they for me not that fast burn it more stron vs burns, than mosfets. For me mosfets often burn, then it is hot.

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.

Why?  The TL494 already has complementary outputs.

These are then fed to the PNP-NPN bipolar H-bridge for current amplification.

Does that bridge have a better performance than integrated MOSFET gate driver (e.g.: UCC27511) ?

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.

Cool.  Is that antenna difficult to tune ?

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

...and what are the dimensions of the secondary winding?

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.

  Yes, it's true that I feel like a kid at times, but not true that I don't take you seriously. As you push others, in the same way I push you. Of course you can do as you like.  I do however appreciate your input, even though you don't find a spoon.

  quote from Verpies:  Concerning Woopy's scope shots.
  "It was a mistake to take that voltage waveform reading without a resistive load in place of the light bulb.

  Well maybe it was, but this was the path that UFO politics used to get his motors working in a very unconventional way. UFO is also able to light several huge 85watt CFL bulbs, giving many lumins, as well, using what he calls "COLD ELECTRICITY". (the green flashing Cfls).  The main thing is the circuit, and how it may be  similar to what Akula and others may are doing. 
I'm looking for clues...

   Woppy's scope shot are meant to show the tuning of the circuit using the two pots and scope, to find the sweet spot, although that is somewhat conventional, the ultimate results are not.
   I use a light bulb to show me the same thing, as I'm not concerned as to what frequencies are shown by the scope. Having the two trim pots is a great advantage though.

  Tinsel:  Thanks for your analysis of the akula devices. That is the point.  Those pictures are fairly clear.
And yes, I'm guessing as to what the diode values are, the point was the current direction as they are pointing towards each other.

  Menof:  Using the single Fet (in woopy's video) is similar to what you are showing in your diagram, it is a simpler version, to look for the working principals. It also shows that a single Fet will work fine, also. Although he is not showing any real gain by it all. That was not the point  when he made the video.
  Maybe one will not see the input readings drop until there is a feed-back path.  Or not?

One man in one forum made selrunner, but with 3 w led bulb 220 volts, but it light on 100 volts. He say that most inportant is LC circuit and generator. And that very hard find exatly needed frenquency. Need with two potiontiometers for example 200 kiloom and 20 kiloom for tune. But very hard find needed frenquency.

    MenofFather:
   Might be a zener diode, but might not be, also. Why are they facing towards each other? Is this really a common way to protect the Fets?  I don't use Fets, so I don't know...  As they can easily fry out, especially when allowing  them to get the high current back emf pulses 1:10 to deal with, as Ismael is mentioning. They are fast switching, but are also weak. Seams to me that special high current and high voltage diodes are what is needed.  No?
