摘要：
A novel zero voltage and zero current switching (ZVZCS) full bridge (FB) PWM converter is proposed to improve the demerits of the previously presented ZVZCS-FB-PWM converters[5-8] such as use of lossy components or additional active switches, A simple auxiliary circuit which includes neither lossy components nor active switches provides ZVZCS conditions to primary switches, ZVS for leading-leg switches and ZCS for lagging-leg switches, Many advantages including simple circuit topology, high efficiency, and low cost make the new converter attractive for high power (> 1 kW) applications, The operation, analysis, features and design considerations are illustrated and verified on a 2.5 kW, 100 kHz IGBT based experimental circuit.
