I need to adjust the mosfet parameters but i dont know where i could get them from. The datadheet of the IRFP250 doesnt mention width and legth of the substrates anywhere.
Anyway the ZVS (zero voltage switching) is a circuit to power center tapped coils with pretty high currents. This is mainly used for induction heaters but as in this case, can also be used as drivers for HV trafos.
