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.

hi apecore,

The other mosfet drivers don't come close for required kacher frequency
For example the maximum frequency for TC44xx series is mere ~150khz if i recall correctly.
The maximum frequency for UCCxxxxxx mosfet driver series is mere ~1.1Mhz.

Both obselete mosfet driver can't handle 20volts supply even at low frequency below 35khz which is required for 1.2kv silicon carbide mosfet for low Rds on.Unless maybe if you use 900volts series SIC mosfet which merely needs 15volts at it's gate. :)

The IXDI inverted mosfet driver series from IXYS Corp can handle up to ~2Mhz easily without the need to use "2 or 3 stage" suitable "pnp/npn transistors" for high frequency mosfet driver.
This one I/C merely simplify circuit design which can also be applicable for sergey interrupter circuit(Frequency control by mica capacitor for high stability). :)

The prototype of mine and Akula interrupter circuit both rely on tesla coil resonance frequency.But Sergey circuit needs to be tuned to tesla resonance frequency and needs higher voltage >150volts for tesla primary coil supply to get to 22Kvpp which is overkill.haha.

Magpwr thanks,
I understand .....
I will try your kacher circuit,.. also because the ground connection is there on the secondary.
This to get the loop complete to gound.
I will look at your YT vid..
But first finish my pushpull ...
Thanks

Two days i was working for nothing. Apecore don't change nothing in your push pull , first put your oscilloscope probe on gates of mosfets and see the signals. If there are clean signals you will work for nothing in gates mosfets, like me.
 After two days I was working for make a big distance between mosfets and make them opposites,  make a small distance  between driver and mosfets gates, i have the same result, a good signal on gates and a lot of spikes on drains.
 That is because yoke give back spikes and  signals that make double the frequency or invert the signal or kill the mosfets.
So, Mr Vierpies  don't give solutions for bed signals on gates , if you can, give us a solution for bed signals on drains, will be ok.
I am sure that 99% of us have clean signals on gates of mosfets but on drains is very bad.
 Lossless clamp kills every signals we need or we don't need, is not so good that lossless clamp for this device.

Conico,
I understand your point of view.
But i take Verpies advice with both hands to get first gates as clean as nescessary.
Sure yoke gives back spikes, we will see what comes out.
I will feed the bemf from the yoke back to the power supply if nescessary,  but this bemf must not be more then normal.
With other words ....max efficiency and minimum input power.
But good to hear that the most important step is the distance driver/mosfet.
Next i will put some ferrite beads as Magpwr said and wich also is mentioned in Verpies attached file.
Scope shots will clearify the results.

 Scop shots can tel you what you already have now, , a good signal in gates without changing your push pull in gates mosfets.
If you want to work for nothing is your choice!

Are you suggesting that apecore's gate signal as shown in his attachment (ref:post 15922) is good enough for this application and if yes, why do you think so?

What if the spikes in the drain circuit are responsible for some "magic" ?  AFAIK these spikes reach the yoke and the grenade and we don't know what they do there.  NickZ will chime in here..
Are you sure you want to suppress drain spikes?  If "yes" then how much do you want to suppress?  ...all the way down to 0 Volts or less ?  How much less?

Lossless clamp kills every signals we need or we don't need, ...
Lossless clamps clamp any signal above the drain power supply rail.  They don't kill spikes all the way down to 0 Volts.

Some of us may recall that "mosfet is able to function well at high frequency" and IGBT is more suited for low frequency.
Yes, MOSFETs are faster but IGBTs can take more abuse in the collector circuit.  Their gates are equally vulnerable.
Also, when MOSFETs turn-on, they act as bidirectional resistors while IGBTs act as unidirectional diodes with 2V voltage drop and all that goes with it.  At high currents diodes become more efficient than resistors.

IMO yoke transformer's leakage inductance will damage MOSFETs faster than IGBTs upon circuit interruption (turn-off), but the spike from the leakage inductance can easily exceed the 1.2kV C-E breakdown voltage, too.  There is no limit to this voltage in theory.
The leakage inductance is the major cause of these voltage spikes.  You can measure this inductance by connecting an LCR meter to the primary winding while the secondary is shorted.  In an ideal transformer this reading should be ZERO.

Q: What causes the leakage inductance? 
A: Badly wound windings and bad transformer builds (e.g. leaky cores).

I am sure that picture show the signals on drains not on gates. If this signal are on gates the mosfets are already burned.

The problem is not to suppres to zero spikes in drains, the problem is the spikes not becomes wave and invert signal or double frequency. We can not tune the devices with an inverted or doubled frequency of wave.

It's better to ignore/supress spikes with beads than to implement unwanted circuit to recover spike.
Which spikes are you referring to?  Gate spikes or drain/collector spikes ?

Span the entire circumference of the core with even number of winding layers (alternating circumferential direction and the same toroidal direction).
