Oh wind me a coil sir...

It's simple

1) Disable one TL494's internal oscillator by:
     a) Removing the capacitor connected to pin5
     b) Removing the resistor connected to pin6
     c) Connecting pin6 to pin14
2) Connect pin5 of the 1st TL494 to pin5 of the 2^nd TL494.


P.S.
I have to ask: Why are you using only one output of the TL494, which has the pins 13 & 14 connected together ?

hi verpies,

I have posted in Akula0083 Light No3 - Dual TL494 recently.

http://overunity.com/14610/akula0083-light-no3-dual-tl494/msg470435/#msg470435

Using only 1 x 74HC132 to drive mosfet driver.The low power/low frequency generator and high frequency interrupter circuit(gates duty cycle in pulse nanosecond) function the same way as dual TL494.

I have tried with flyback core from other brand and Sony ferrite core which match the ferrite  core used in Akula video.Both produce same results.

But like said i do suspect Akula did tamper with ferrite core to create maybe some fractures or cavity within ferrite core.Either by putting core itself in ice then dumping it in hot water or heating core by fire then dumping it in water.I have no time to try this yet since i am almost always involved in experiment.

But those want to go further may want to try 2 identical set of flyback core then characterize 2 different core after carrying out the treatment as describe above.
I do suspect the cavity/fractures within core is the key.

I won't discuss about it further to avoid detour in this topic.Time for soldering Oleg+sergey interrupter circuit today.

The wild guess - https://www.psiram.com/ge/index.php/Steho_Energy_AG ?

Does anyone know the patent number for this "Combined Rectifier" device?

Found it:  Combined Rectifier   EP 2 387 142 A1  (attached)

   Hoppy: Ok thanks, 1500W TVS. So, will they help at 10000V but at low wattage from the Kacher or HV circuit, which is induced into the induction circuits, and still able to keep the fets happy? Maybe that not a problem? But, it seams to me that some of the burn outs, that some of the guys are experiencing may be from the HV interaction, and not "BEMF". 
 

Nick,

The TVS I'm referring to is rated at 1500 Watts, not volts, so yes, any voltage spike over its rated voltage, say 100V, will be clamped.
