   Void:
   The Siglent scope is the 1052DL.
   

   Itsu:  I have not been able to get the "effect" back with the snubbers on. So, I'm seeing what can be done about it, as the snubbers are needed, but then so is the effect.
   As it looks like some ringing is still needed. But, not too much ringing, and not too high a peak (under 230v, or so). So, I'm looking for a compromise on the snubbers.  As it looks like the snubber resistors, both the Oleg snubber resistor, as well as the RC resistors still get hot.  But they do help with keeping the fet's extreme overheating temps down. So, I'm working on all this now.

Hi Nick,

ok,  understood.
So for the effect to happen you need some level of avalanching in your MOSFET(s), so using a higher rated MOSFET (IRFP460) will not work either
as it will avalanche only at a higher (>500V) voltage peak.

This way, i think a selfrunner will not last long as the avalanching MOSFETs will pop eventually.

   That may be, but Ruslan, Akula, and other guys are getting their systems to work, so there must be a solution, without a meltdown of components from the Kaotic mode.
Perhaps a slight not too extreme avalanching is what is needed, with some ringing on the flat top of the square wave, as Stalker shows. Or possibly just being able to hit on the effect without avalanching the fet(s). I think that I showed that in my next to the last video. Where the Kacher is having an effect on the induction circuits, but not going into the total kaotic mode.
Otherwise the Kacher produces no effect on the induction circuits, and no additional light nor output is to be seen from their interaction when in the "normal" mode, at all. As most guys have seen.

   Watch Geo's 2 videos where he is replicating Urfa's way of doing it. You can see that at first video, there was no noise, but in the later Urfa replication video you can hear a very slight higher pitched ringing. So, he was getting the effect yet his fets were cool. And his device was very similar to mine, as least when he showed those videos using his simple kacher circuit.  His newer controllable Kacher circuit he has not shown running, yet.

Nick,

One big difference between your setup and Geo's is that Geo was using really big heat sinks on his mosfets. It might be worth changing yours to see if you can get the 'effect' and stay cool.

  Neither bigger heatsinks nor fans can keep up with the avalanche mode.
   I had big heatsinks on the Mazzili, FETs still got too hot while running 50% duty cycle.


  Maybe the avalanche is not needed to see the effect. That's what I'm looking into now.
Ruslan's heatsinks and fans are no bigger than mine are. So...
