Kapanadze Cousin - DALLY FREE ENERGY

I saw increased current and like you, one very hot mosfet.

Yes, if the input current from the battery to the PWM increases a fair bit when the lights get brighter, then
as we have discussed in the past, that is probably not the kind of effect that we are looking for.

Void,

it has always puzzeled me how Ruslan was able to show, on video, that 90° phase shift when activating the Kacher only.
For me the saturation of the the CT would be stable, so always there with or without the Kacher.
But apparently he was able to balans it such a way that the Kacher had that effect on the phase shift.

Yes but A clamp meter can be used to monitor the ground current should tell us exactly what we want to know. Would it be possible to go that way assuming the device has no other form of earth leakage to another earth connection?

Yes, that is a big mystery for me as well, which is why I was doing some testing related to that.
Even at very low power using a signal generator with only a FWBR and capacitor as the grenade load
(as I believe Ruslan was using in that video), I can get the same sort of summing of the two waveforms
using a grenade coil wound the same as Ruslan showed how he winds it in one of his previous videos,
but I don't see that extra 90 degree phase shift when the two waveforms are summing. BTW Ruslan was
running his PWM at either 37.3 kHz (shown by his scope) or 34.2kHz (shown by the frequency counter on
his DVM), and his tesla coil at 1.74 MHz (shown by his DVM) in that video.

Probably I need to test further at full power to have a better chance to see that sort of phase shift effect. That extra
90 degree phase shift may possibly be a key, assuming what Ruslan showed in his demos was legit. I so far don't
have an idea of what could have caused that 90 degree phase shift when he switched on the tesla coil however.

Blue trace is the current waveform from the CT on the series resonant current loop.
Yellow trace is the output voltage waveform of the grenade coil.

Nick,

i understand your excitement, but without proper snubbers, you probably hit like Void and Hoppy mentioned some oscillations / feedback (chaotic mode).
It will unbalans the yoke- and TL494 system and cause all kind of effects   ( i had my near by temperature controlled Weller soldering system shoot up to 500°C).

But be welcome to further explore this, and a video would be very nice to see.

  Well, the thing is that unless it goes into what we'll continue to call the Kaotic mode effect, there is no extra light at the bulb(s), when the Kacher is also connected on. So, that is the only frequency point, the only sweet spot that I've found that will increase bulb brightness. Otherwise it's a no show.
   The reason that the one fet gets hotter, is because that's the one that is showing a higher peak. And when the effect kicks in, the voltage goes over 250 volts. Therefore that the one fet get hotter than the other one. And the other one stays much cooler. And yes, there is higher draw from the PS.
   But, when you see and hear how moving ones hands near the grenade's antenna coil causes that unusual sound effect, that could not be replicated without that Kaotic mode in action. You'll know that something different is going on there.
Yet, it's a very very very narrow tiny bandwidth where this happens, and is why it's so hard to find, and maintain. As any additional bulbs, tuning caps, ground connection and such added to the system can throw it off. Even ones body being close to the device. Or the placement of the yoke, etz...
  So, more tuning is necessary to really tune into this Kaotic mode.  And yes, we've been there, done that,  next.
   But, this ain't the same ol thing. As I NEVER heard Radio Moscow, before.
