Dear apecore.

I have attached a picture that Nick posted many pages back, it is a close up of the snubbers.

You might find that fitting a Varistor will help reduce those high voltage spikes.

Kind regards, Graham.

NickZ, can you give me a link or a diagram of that Roma device  ?

   Connico:  You'll have to ask Roma himself for the right schematic to his self runner. As that is what he was selling for $1.500, or so.  A working device was something like $3.500.  He is not open sourcing his device. But, there are diagrams that are on the internet, which may or may not work. As they are not from Roma, nor from anyone that has been able to replicate his device(s).
However, there is a  diagram from a guy that bought some schematics from him, but, it's not the same as what Roma had been showing in his videos. And Roma is not showing anything else, lately, and may have taken his videos down, as well.
I don't know if there have been any replications, using that purchased diagram, or not.  I do have some of those diagrams though.

Dear Graham,

Thanks for the responds, unfortenately it does't work or maybe better solves the problem
i added a varistor150Vdc and same thing occurs.

What i do see after some extra monitoring of supply voltage is that the kacher system not only radiates HF into my TL494 circuit but also pollutes the supply volage true the whole system.
So by putting some aluminium shielding in order to elominate the kachter radiation reduces the radio noises out of fets/ yoke wich reduces some of the spike polution on the source/ drains and also gates.

But the 10 mhz waves 1 or 2Vpp on the supply voltages stil are there.
So i gues i have to work on some net filtering

  apecore:
   You can maybe try to place a diode on the power supply so that the spikes don't go there? However the spikes are all throughout the whole system. A proper tuned 37.5m grounding line helps to reduce that.

   The varitor on the Akula second video schematic normally goes between the 3t coil and the 28t coil, so that the initial turn on won't rush too much power at turn on, and so that the power will turn on more slowly, between the coils. At least that is what I've heard.
   10MHz is very high frequency, what is providing for such high frequency?  Or are you thinking 1MHz, instead, from the Kacher's output?
    Some spiking is normal, but not over the IRFP260N fets voltage rating of 200v. But, if a very low duty cycle is being used, some higher spikes may not be too destructive. Like Verpies had mentioned previously.
   
   Have you been able to get the Kacher to sync with the induction circuit, and to provide for brighter bulbs?

    I'll call you later today...

This is an experiment that I did with a TV yolk wound like Ruslins.
I'm not sure what the yolk came off of,  (TV or Computer Monitor).
I used my Geiger counter to monitor the yolk while I changed the
Driver's frequency and voltage. The video shows the test results.
The results are inconclusive due to lack of better equipment, but
Still interesting. I have another yolk that is different, that I can try,
And see what the results are.
