Abstract :
A latest super-junction MOSFET is applied to hard switching, high power PFC application and compared to soft switched IGBT. With reduced on-resistance and enhanced switching characteristics, the super-junction MOSFET can compete with soft switched IGBT. A 1.5kW rated CCM PFC circuit is designed and ZVS logic has implemented for performance evaluation of both configurations. Limit line of power rating is discussed through analyzing switching and conduction losses.
