Kapanadze Cousin - DALLY FREE ENERGY

Seems that all such solutions require active powered isolated gate drives ?

Yes, but the optocouplers cannot power the gates in the photovoltaic mode so they require a secondary power supply for the gate currents, too.

How much slower is the one without the active power but with photoelectric effect inside gate driver ?

30ns vs ~8μs.  I attached the link to their datasheet in my previous post.
However, the speed difference is not the biggest advantage of isolated vs. non-isolated gate drivers.

Your dead right about Led GalSi opto's they get hot and crack but I was a bit confused on what you had invented but I think your talking about HI side Low side Driver chips,

The Hi-side vs. Low-side distinction does not exist with isolated drivers.

like IR2113 family and 2 N-channel Power output stage Fets.

No, I did not mean those drivers.  I posted a link to the datasheet of the isolated gate drivers in my previous post.

They still blow up though but you can do a circuit that limits the current flow in the FETs but it has to be dead quick.
P.S. It would be great if can you come up with a circuit for that ?

Drain current limiting circuit is a very different issue than these gate driving circuits.  How quick would it have to be anyway?

[verpies]

What does it do except making short high voltage pulses ? 
What can it be used for?  I don't understand it.

In a nuthshell, DSRD pulse generators are able to generate a very dense frequency spectrum. Tesla coils cannot do that.
See here for an English description, maybe that will help you understand it.

  The amplification "effect" is noticed when the Kacher's output is added to the induction circuit's output. Or not noticed.

There is absolutely no evidence that the 'effect' we see (for example on Geo's and Urfa's videos) is an amplification of real power, resulting in 'more out than in'. How can it be evidence when nobody has measured the power dissipated by their respective lamp loads to compare with input power. I'm not saying that you necessarily believe it is a real power amplification but the word 'amplification' needs to be clearly defined when used in this context.

That's only an illusion because P-ch MOSFETs have roughly 3x higher R_DS-ON and are more expensive and less available.  Also the resistors in the gate voltage divider will need to be high power ones for a 300V secondary supply.  These resistors have to be special non-inductive power resistors and they will heat up strongly, too.
Last but not least, the gate voltage divider will not be able to charge and discharge the gate very quickly so the switching speed will be limited. 

Hi Verpies.
Wow! You put me on fire with this. A universal driver is always useful and it also would be a nice project. Perhaps in the near future I could give it a try.

For now, I'd like to set up a quick side experiment using negative pulses. I want to use all the collapsing energy, without damping it to the power supply or to let it be absorbed by any capacitor. My dc pwr supply would be at 24V and not at 300 as it is at the attached image. I just used it as a reference. 24V at 40Khz is my target. How can I calculate the current I need out of my 24V batteries so to charge and discharge quickly my gate at 40Khz? Is there any equation? I need it for finding the optimal resistances range for the divider. For protection i will follow the protocol (zeners etc.). Probably, I will stuck two or three p-mosfets in series for getting higher avalanche voltage and letting this way the pulse to be developed freely. Just some capacitors are needed for synchronizing all mosfets together.
