Abstract

In This paper, A novel zero-voltage-switching(ZVS) resonant DC-DC converter is proposed. it is composed of two symmetrical active-clamped circuits, The converter can achieve each switchs ZVS. proposed circuit is active clamp capacitor Ratios can be reduce switching voltage stress of each main switch. Simulation results using Pspice ver 9.2 show that the prove the validity of theoretical analysis.
