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??

Itsu:
    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).

Hi Hoppy. Kapanadze was doing some things in that video which I couldn't follow.
My impression was the battery was still connected to the inverter box whenever
the device was running, so I couldn't figure out why sometimes he was plugging that
plug in the AC socket.

Kapanadze seems to make some comments about the sparkgap in the video. Would be nice to
have a translation of what he said about the sparkgap or any other technical details. Maybe in
those earlier days he was a bit more forthcoming about some technical details. :)

In case anyone is wondering which video I have been referring to, it is this one:
https://www.youtube.com/watch?v=Tj3neKg5KMc
Seems to be about 80W input and possibly 4 to 5 kW output with a very simple setup.
Yeah what about that video? why did you pick that one? why not the other one with all the sub titles? Hmm or yet another one shows in side the stack of tobacco tin ?? the transformer is in the loop 240 to 12v on the input drive, why exaggerate and ignore the truth ?? I mean what if your arse was your elbow what then. Try thinking out side the box for once.

Like this one for instance https://www.youtube.com/watch?v=lmM7OyudbvY

Hi Hoppy. I don't know, but it appears the battery powered inverter that is supplying the 50 Hz, 220v, or whatever they use there,
is the main and only power source needed once he gets it going. It could just be that the inverter he had couldn't supply enough power
at startup to power the whole circuit and the flyback driver circuit at the same time without a temporary boost from the mains to get the
sparkgap going. Not sure at all though. Just going by how it looked to me. :)

Anyway, there seems little doubt that if that setup was genuinely producing OU, that it is a relatively simple setup,
so possibly it is a fairly simple concept behind it once you know what it is. :) Thanks for the chat Hoppy. I will get back to
doing more experiments along these lines over the next while as I find time and see what happens.  :D

All the best to everyone with their experiments...

   OK.
   But, I'm doing what I can with the spikes, as otherwise,  the FETs are toast, as they are going  over two hundred volts.  I won't have the new FETs till tomorrow, though.

have you tried getting a discount for bulk ?

If your serious about just clipping the spikes try a version of this Voltage 'limiter' but don't dump it to zero volts, put it back in the system via a small value 'Resi' ok ((short it out to zero volts right or it will just over heat it and the mos fets)).

look under 'transient voltage suppressors'

If Nick continues to use 200V rated mosfets, he will very likely need to use transorbs, especially when he removes the 24V lamp current limiting resistor and runs straight from his 24V PSU.

   Itsu:
   Here is a scope shot of both expanded ringing signals, now, with a single 222 capacitor installed between each drain and source.
   The volts/div knobs set at blank (50v?), and sec/div is at .2us. 
   So the ringing signal between the two first peaks is now at 2.5MHz? Correct?
   The lower scope signal is the fet that was heating up previously. It is still showing a higher voltage than the upper (cool fet).
   
    I think that just with the 222 caps on, that has dropped the frequency by about 1/2.  The scope signal shows TWO divisions now, instead of the previous just ONE division. Highest voltages peaks now below 150v. Down from over 200v.
So, in the safe limits, hopefully?
   Let me know what you think, and also what resistor to place on the snubbers, also.  10 ohm resistors, maybe?
   This was done with me using two older fets, so that I could continue working on tuning these snubbers last night.
The new fets will be picked up later today.

Nick,


i think your blurry picture of your scope shows it is set at 2us/div. not 0.2us.
So this makes the time between the 2 top pulses 4us (2 div.) which is 250KHz.

So the ringing i see is of a 250Khz resonance signal, which is about 1/8th of your ringing signal without a cap (1.98Mhz), which is way to much as we need 1/2.

Concerning the expanded ringing screenshot, this is a strange signal and i also need to see the un-expanded signal as i now have no idea where/when this ringing
occurres, at turnon or turnoff time.


I think it is better to wait for your new scope / new MOSFETs so we can have high quality pictures of a good situation.


Thanks,  itsu

Sorry if this was already checked
But didn't Tinsel say that the ground "buss" is a common cause of this fuzzy view on older scopes ?
 
to repair ,  clean all the chassis grounds and reattach ?

apologies if this was already tried.
