ZVS driver charging capacitor bank
I tested some of my theories, ( and blew some mosfets up...) but in all of my circuits the problem was that the secondary windings were made out of too thick wire, so the resistance of the secondary was around 1.1ohms, I tried to connect (highest wattage I found was 470ohms and 3w (was too small, some bluish smoke came out)) and it started the oscilation. then I re-wound the transformer, with much thinner wire, the resistance now was like 34 ohms. now even with the capasitors attached, it starts the oscilation. the transformers had (the first with too thick wire, 5+5 on primary and about 260 on secondary, the second transformer has 6+6 on primary and around 250 on secondary. Hope this helps
