Power converters free delivery possible on eligible purchases. If you are using a full hbridge or halfbridge the body diode of the other mosfet the one not switching will act as a flyback diode, however the power loss may be more than through the mosfet since the motor run current multiplied by rdson can be less than a diode drop for a good mosfet. Introduction the mazilli zvs flyback driver is wellknown throughout the high voltage community for its simplicity and ability to deliver 2050 kv at high currents for a flyback transformer. The 10 ohm resistor charges quicker, much quicker, and so, the rise time is very small as compared to the 2k resistor which limits the current, thus making the capacitor take longer to charge. Its based on some work by the people at rmcybernetics on ignition coil drivers, and it seems to work fairly well. Mazilli zvs flyback driver kaizer power electronics. This driver rectifies mains and produces a 320v dc source.

I installed the mosfet on a old cpu heat sink with fan, the 555 timer circuit is also installed underneath this heat sink, its then all put on the side of the flyback transformer with wire strips.
