The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
I've built the ZVS flyback driver, and it works great. But there isn't any desciption on this forum (nor the net) about how it works (or I could not found it). How it realises the zero voltage switching, etc. ? Thanks for help.

This simulation is not showing the normal operation of this circuit. The output transformer seems to be ideal, the series inductor (63 mH?) is far too large, and the waveform shown does not make sense. A more realistic simulation: Essentially, this is an oscillator that resonates the capacitor across the two primary coils with the coils.
