No. The fet only provides the sink, the resistor provides the source. You would need very low value resistor which would mean huge power dissipation in that resistor in order to get the switching time good enough.but why? doesn't the one FET provide source and sink of charge for both power FETs?
ah, but shouldnt i see a higher V than ~12v ?Don't forget about the body diodes in the fets. They are most likely conducting and dumping the inductor current back into the power supplies.
Body diodes behaviours just like an ordinary diode connected between drain-source.ah, but shouldnt i see a higher V than ~12v ?
Can you uplaod the LTspice file?even with diodes the voltage rises very high (540v) but didnt reach diode 800v reverse v rating, FET still shows some reverse current. let me snub it with a zener.
