Abstract :
A novel switching control method for soft-switching DC-DC converter is proposed. The proposed control method is keeping the zero voltage switching (ZVS) switches off until snubber capacitors discharged. This method is simple and effectively achieves ZVS at light load. Without adding any auxiliary resonant component, it can provide compact and high efficient converter. Furthermore, by taking voltage fluctuation into consideration, the control method can achieve high reliability. This proposed method is applied to soft-switching DC-DC converter including ZVS arm
