摘　　要：本文讲述了双晶体管正激有源钳位软开关电源的工作原理,并给出实际产品双晶体管的工作波形。该电路结构中,功率开关管的电压应力小,并工作于ZVS导通和关断,减小开关功耗,降低了EMI。The operation principles of the soft-switched power based on forward active clamp dual transistors are illustrated in this paper. And also, the operation waves of the dual transistors in the actual products are presented to testify the performance of the power. The proposed power has the advantages of smaller power consumption at on/off state and weaker EMI, due to the smaller voltage stress on the power switches.
