I did some more experimenting with the 'URFA effect' and I now know that he has his kacher tuned for maximum spark length and current consumption.

Don't you think that powering our kachers straight from output voltage (in parallel with bulbs) would be the most powerful method without any implications to any other stage especially to mosfets?

Secondly. Isn't just a TVS diode enough to synchronize katcher at a peak voltage, which conveniently will be the calculated TVS's breakdown voltage?? If for example we have 100v output voltage under load, we can supply katcher through a TVs with a threshold voltage of I.e 80v to 99V.
With this way we will have sync, plus power. Just some modifications at base side. I think i'll give it a try.

Anything is worth a try. I've just tried the configuration posted above by Menofather. it don't work for me. No bulb lit and no Kacher output!

Hi Jeg & all,

Its great to talk with fellow experimenters in this community. Nothing ventured, nothing gained.

I've been looking closely at my Karcher waveforms and comparing them with those in Ruslan's video posted earlier by T1000. Mine are not quite the same and I think this is something to do with our Kacher builds being different. I'm fairly sure that although he is using what appears to be a common-mode choke, the two coils are not connected to work common-mode. We need more detail on his oscillator circuit in order to replicate accurately. Another puzzle solved for me, is why Ruslan's scope was showing 3.16293MHz, when mine is reading half that frequency. The puzzle was solved when I realised that I needed to disconnect the antenna and then found that my scope read around 3.2MHz.

I did some more experimenting with the 'URFA effect' and I now know that he has his kacher tuned for maximum spark length and current consumption. The reason that the lamps dim when his hand comes close to the antenna is that the Kacher secondary voltage increases, causing a corresponding increase in current. This current 'steals' current from the push-pull oscillator, which in-turn reduces the induced current in the 28T yoke / lamp load circuit. However. I'm still intrigued at how sensitive his antenna is to hand capacitance. The total supply current actually increases when the lamps dim! URFA clearly has his device tuned very differently to Ruslan's.

Do you know what he was adjusting to get this sine wave like signal on the collector?

  Hoopy:
  " This current 'steals' current from the push-pull oscillator, which in-turn reduces the induced current in the 28T yoke / lamp load circuit."
                                                                           end quote.

  And it can also un-sync the Kacher/grenade frequencies, as well, further causing this dimming effect.
 
  Jeg: I think that the idea of feeding the Kacher directly from the grenade's output may not work very well. But, try it and see, maybe there is a way to do it.

    John.K1:  Depends on which video we are referring to, as the one that I viewed showed no dimming of the bulbs, even when Ruslan's hand gets very close to touching the antenna coils.  I"ll see if I can find that video, later.
  I also feel that Ruslan's latest PBC is "nothing special", and can possibly already be obtained and ordered, if we only knew where to look for it. Along with the duty cycle/frequency control board, as well.  There are several high output induction heater circuits boards, ready made, along with the adjustable controller circuit boards on the market.

  The best Ruslan replication of the second Akula device, is the one in the link below. Using a 12v battery to start it going.
  Notice also how when he adds the 4th bulb, it dims all the other 3 bulbs. And he probably can't even start his device with all 4 bulbs on, and needs to add the last one after it starts.
I estimate the lumin levels at less than 500 watts total compared to a grid source.

Good question Itsu! I could only see his probes connected to collector and base. However, the sine wave like waveform he shows is not from the collector as far as I can tell from my scoped waveforms. The nearest I could get to his waveforms was to adjust the bias resistors to give me his top waveform as scoped at the collector and bottom waveform as scoped at the base. This was opposite to what I had assumed before my scoposcopy.
