Phase Shifted ZVS SMPS Descrete Circuit

This is a classic implimentation of phase shifted zero voltage switching smps usind descrete ICs.
Controll circuits implemented here is same as popular IC UC3875. Feed back is provided for both current and voltage for constant current current constant voltage application. Isolated outputs are provided using pulse transformer for driving MOSFET or IGBT. Fault current trip is also provided for protection appart from constant current limitting
