Hi Vala, People,

Here is Vala's circuit converted to picture.
Interesting fet driver

Thank you.

not eng.

I think, that vala is trying to control FETs with impulse trafos which I think is good approach
scince we don't have PNP optocouplers in our shops to make discrete solid state relays and be sure when actually our fet is closed or opened. So this is the next best thing before we manage to buy some real solid states (no triacs or SCRs at output).

His schematic approach is novel in that manner that he uses parallel-serial,serial-parallel recombination of caps but allso uses part of my last schematic that helps to discharge serial combination much more (and in same time preserving dipole from otput) than just recombination would allow.

I wellcom this approach but there is one additional loss when charge is splited to paralel capacitor combination it losses it's potential (V) and much of energy is lost that way so I wold stick to complete detail in my last schematic.

goosh I don't have time to make this simple setup.

DobÃ...â,,¢e, skus to otestovat.

OK, now we have to test it !

If building uppon schematic with only two caps (the one I recently proposed) it is advised to use
unipolar capacitors (sadly known unipolar caps have small capacities).electrolites will blow.

Are supercaps unipolar or bipolar caps ?

l am sorry at present have not time.

Capacitor RAD BIP 10/100 RM3.5  (www.ges.cz)

It is whim synchronic resonance.
Heed not regulation (R3= 10K - 1K) max 60V
R1 = (In) or out energy.
Start charge T1 (primary - sekundar)= coil capacitor
Deepr analysis next week.

Sorry not englich.
