Kapanadze Cousin - DALLY FREE ENERGY

I finally made my new push pull board. It is the same as Acula's classic one but with better component arrangement on board. I noticed for first time this Gray zone that we were talking about. Thankfully i already knew the reason!

Good job Jeg! Will be interested to hear how it performs once you have had some time to
do more testing with it.

Hi Void Yes of course.
Just to express it right, i meant it is looking better than my ex-driver board which was the same TL494, IR2110 driver. The improvement is a 12V zener connected at base which made my gate pulse cleaner. In addition, i re-calculated the snubber values, and i also incorporated a 200V TVS between drain and source. Nothing special mate, i am just trying to end this chaotic mess over my bench by making my boards smaller. I'll make a video when everything is set for another round of tests.

Hi Jeg. Yes, understood that it is a new and hopefully improved version.

Presently i am changing the snubber setup to use a RC configuration as calculated by this website (using my 1.4MHz ringing):

Hi Itsu
Do you remember the value of cap that you connected between drain and source which leaded at the half of the ringing frequency? (At my setup i had a 1.35MHz ringing and i used a 2.2nF to bring it down at almost the half. So my parasitic capacitance calculated at 2,2/3=733pF

About frequency multiplier and Tesla coil - you can force it to work as normal high frequency transformer. The ferrite filter choke between TT and top load have to chop sine wave into spikes anyway. It will be not so efficient as in natural frequency but still will do a job.
About Ruslan explanation - I mentioned before about low resistance resistor so you can get on which frequency it wants to run for maximum current over resistor.
Now from Roman(akula) private conversation 2 days ago - the way he understands grenade coil the equivalent is choke with capacitor in series. The bucking coil make capacitor function within. The external electric field is charging them like 3 plate capacitor where 3rd plate is TT top load. All you have to do is to sum all energy within grenade coil which got strong magnetic component with strong electric field from TT  in resonance then you can extract more energy than you put into grenade coil.
And when clarifying bits with Roman we talked same language so we' RE on same track. He loved idea about frequency multiplier so his part of the deal was to give me explanation how he see fundamentals working in device.

Cheers!
