How do i stop thous drain spikes?

Hi Conico
Snubber calculation is necessary. Use this calculator. Have fun!

Conico,

Ruslan also uses IRFP260 (200V) or even IRF3710 (100V) MOSFETs, so IMO these 380V spikes should not be there for a good working device.

The Oleg designed snubbering did not work for me (or Jeg), so a properly designed/calculated snubber circuit as linked by Jeg did the trick,
but it had some side effect like unwanted RC times during opening/closing of the MOSFETs.

The lossless clamp design from verpies should be able to handle these spikes but even then a proper physical layout is mandatory.

I see a lot of long wires between your yoke and MOSFETs, also no MOSFET driver chips are seen on the MOSFET board, so probably they are in the grey box
meaning long wires = extra inductance.

What you are saying about yoke and grenade needing a 90° angle for "the effect" to occur sounds somewhat vague, it more sounds to me there is (unwanted?)
oscillation going on when components are placed in a certain position.

My inductor also ran hot after some minutes, but that seems normal as there is 50A running around in that series LC.

Hmm! all this reminds me of Eric Dollard lectures, and DC and motors, Ever wonder why electric motors run so hot ? it's because the energy fly back (radiant energy if you like ) is wasted in heat, can't you drain your spikes of back into the system, ans does the plastic pipe get hot and 'warp' ?

Nelsonrochaa knows how to do that
But he 's bin here long time agoo.

   Itsu:
   Good to see you back. I think that it's safe to say that we all missed you here.
   
   Have you given any thought to restarting your tests and trials on your set up?
   I feel as you may have been very close to having a good working system, but possibly a simple wiring re-connection method may be all that is needed. As there are several ways to go about that on these devices.
   
    I don't see any spikes on my device. Just a normal sine wave, interposed by the HV, top of the same normal sine wave signal.
    My inductor does not run hot, but the yoke does heat up after a few minutes running. But, not so hot as to melt the wires.

   Main thing that I'm seeing now is, that when I have a load of 3 100w bulbs running off of the 3 turns coil's 0.47uf cap, and I add another 100w to the same output, there is no change in the first three bulbs. Similar to what Geo had shown.
So, that is where I'm working to take some of the output to use for a feed back loop. Connecting a laptop charger to that same 3 turns coil, did produce a use able input for the Kacher circuit.  But, I'm still working on all of this.

   Any way, it good to see you posting once again.
