Kapanadze Cousin - DALLY FREE ENERGY

[Hoppy]

Are you being sarcastic there?

Not entirely because I think we both agree an 'out of the box' approach is worth exploring.

As you have said, its not easy to work out what he is doing, so it boils down to individuals interpretation.

He is not connecting the mains directly to the coil unless it is an outright fake.

Anyway, it seems there is little interest in this any more, but the Daly and Akula circuits
and info are maybe the best clues anyone has to try to go on regarding Kapanadze
type devices. 

I would be curious to know if anyone has ever confirmed that Kapandze's coils
are definitely air core, with no ferrite or iron core of any type inside?

I agree, clearly not directly to the raw mains supply unless its an outright fake. I'm thinking in terms of transformed down unrectified mains being subjected to HV pulses. As you mention, its odd that he connects directly into the mains. If the inverter is supplying the mains to a step-down transformer but does not have the energy to start the bulbs, does the direct mains connection trigger the process by heating the filaments to then allow the 'processed' inverter output to maintain a fully lit bank of bulbs. Could the buzzing be an out-of-phase reaction of the grid mains somehow mixing with the transformed mains??

    Once I install the new fets, later today, I'll take some more scope shots of the ringing wave form. And I'll also include some scope shots of the 3t/inductor, and/or grenade output wave forms, as well.  As what happens at the output side of things is also important to note. I normally tune by watching what happens at the bulbs, also.
   
   I think that the last peaks on the my image that I had posted, are when the fets are already failing the grade. It doesn't take much for the fets to get off, but still work to some degree. Anyway, I'll know more about the ringing frequency later.
But, I've been trying to get the peaks down under 200v, without killing the ringing.
   
   The digital scope should be here any day now, I hope.   Can't wait...

Ok Nick,   keep the 24V bulb in the 24V line first to protect the new MOSFETs.

Not sure what you mean by:  "I've been trying to get the peaks down under 200v, without killing the ringing"
I don't think that will be possible as the peak and the ringing are connected togther, kill the peak, then you kill the ringing.

Cant wait either for you to show us clear screenshots of the gate and drain signals.   Make note on the max input voltage on your scope, probably its mentioned beside the
input channels.

Whats all this then ?  found over voltage protection for fets circuit it has errors but drawn in Over Voltage VDR whatever you want t use. (however, this is the DC to DC but will suffice).
