Abstract :
A zero voltage switching (ZVS) PWM power converter family is obtained by using a new ZVS PWM module (ZPM) with a saturable inductor which prevents the diode junction capacitors and the commutation inductor from resonating. The new converters show almost all the characteristics of the conventional PWM converters. A boost ZVS PWM converter is applied to a power factor correction circuit. It operates on a continuous conduction mode. Experimental results for output power of 1 kW are presented
