实现串联谐振变换器高可靠性工作的新颖电路

An Updated Circuit to Realize Highly Reliabel Operation of SRC

以“电路故障恶化理论”￣［８］为基础，深入研究了串联谐振变换器（ＳＲＣ）理论和工作原理，提出了一种彻底防止共同导通、单端工作的（ＳＲＣ）新颖电路，并从理论上证明了它的正确性。还提出了模拟高频开关变压器初级电压的实验电路。

Based on FDT(Fault Deterioration Theory)and SRC(Serial Resonant Converter)theory and operation principle ,an updated single-ended SRC circuit wihich can fully prevent switch tube from con-ducting simultaneously is presentecd,and its frasibility is theoretically proved.An experiment circuit to simu-late primary voltage of HF switching transformer is put forward.
