摘要：
A novel zero voltage and zero current switching (ZVZCS) full bridge (FB) PWM converter is presented to simplify the circuits of the previously presented ZVSCS converters, A simple auxiliary circuit which consists of one small capacitor and two small diodes is added in the secondary to provides ZVZCS conditions to primary switches as well as to damp secondary rectifier voltage. The additional clamp circuit for the secondary rectifier is not necessary, The auxiliary circuit includes neither lossy components nor additional active switches which makes the proposed converter efficient and cost effective. The principle of operation, features and design considerations are illustrated and verified on a 2.5 kW, 100 kHz IGBT based experimental circuit.
