I updated the PDF attachment above.  So just download it again.

Ok thx.
I see you added some specific pages.
I do some homework on that, my goal is to secure a steady and as clean as possible signal on the system.
Which will be consistent on the whole tuning range.(1)
After this we start finding the effect and see what power ratio In/Out will occurs.(2)

Greetings

I thought some of you were investigating the spark idea ? How is it that everything we see that appears to work, uses that phenomena, strange that! 'ain it',  'eah'!

AG,
That could be trough.
It is of course the cheapest way of interrupting the kacher signal, but does not goes in line with the timing as wich is held as critical too?

Maybe this also is a good point to discuss, there are also simple methods to let the sparkcap fires at the right moment if that is unavoidable.

The Turn-On Delay time is 17ns for this MOSFET and the Rise Time is 60ns (with 10V gate pulse and 1.8Ω gate resistor) so 250ns is plenty enough to turn-on this MOSFET, but in reality the current in that spike is probably not sufficient to fully turn it on.  However a halfway turned on MOSFET is not happy either because its Source-Drain resistance becomes several Ohms and leads to Joule heating according to i²R.
Gluing the drivers to the MOSFETs will help a lot, but you must also shield the high-impedance inputs of the drivers with a twisted pair or mini-coax.  The drivers should have low ESR (non-electrolytic) capacitors soldered right across their supply pins, too.  Ferrite beads or mini-chokes are recommended too, before these capacitors.
As usual, shielding, short wires and Starpoint grounding are a must, too.

Also, you might want to use other techniques described in the attachment below.

hi verpies and apecore,

There is a simple reason why IGBT is recommended over mosfet which i had found out the hard way maybe 6...8 months ago.Even the 1.2kv silicon carbide mosfet can be destroyed.
Some of us may recall that "mosfet is able to function well at high frequency" and IGBT is more suited for low frequency.
IGBT eg:50N6S2(There are better IGBT created and can be used) is the best option if we don't want kacher or tesla coil high frequency to effect yoke driver.
It is the main reason why Akula used IGBT instead of Mosfet.But i don't care if you don't buy my story.

If we don't want high frequency spike in IGBT gate just put 1 or 2 tiny ferrite bead through IGBT gate pin and IGBT is place close to  mosfet driver ground and output.
It's better to ignore/supress spikes with beads than to implement unwanted circuit to recover spike.Not forgetting snubber circuit the usual Akula design eg:youtube :sanjev21  pwm circuits

---------------------------------------------
I have just drawn  a version 2.0 of my high efficiency tesla driver circuit with interrupter capability(Prototype) for upload in my youtube channel:sanjev21 within 48hours.

Imagine this using 2.0 circuit  at 12.8volts supply i am able to achieve 9.5KVpp and at 24volts i am getting 12KVpp at 110 turns output just below 2Mhz (test tesla coil -Akula design with high Q winding at top half).

No more high voltage supply eg:60volts ...100volts or 150volts needed.Fewer winding is needed to achieve the desired voltage at driver yoke/toroid.

This prototype circuit base on my experimental knowledge is the highest efficiency tesla driver ever created in the internet and this information i can give for free in due time.

I do find it strange no one ever mention  "reactive power" in this forum or maybe i might have overlook in comments.

Magpwr,
I will try the IGBT too.
Your kacher circuit has a excotic driver IC...is there a reason why you choose such a type?

Reactive power.....long long time ago i posted a pdf about the bifillar capacitor coil in combination with spark gap.
LC timing could be adjusted at the pushpull frequenty in order to get the same proces as the sergey interruptor.
