Abstract

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