摘要
在对有源箝位单端正激逆变电源进行计算机仿真和波形分析的基础上 ,研究了电路实现软开关的工作过程 ,推导出了电路实现软开关的条件和死区时间的取值要求 ,并指出变压器一次侧或二次侧回路串连电感应合理选择 ,既要保证小电流条件下可以实现主开关管的零压导通 。
On the basis of computer simulation and simulation wave analysis, the soft switching work procedure of the active clamped single end forward inverter is studied, the soft switching condition of the circuit and the requirement of the dead time are derived, also a principle is pointed out that the value of the main transformer primary coil or secondary coil's serial inductor must to be selected properly to ensure the primary switching tube's soft switching and at the same time not to reduce the output power of the inverter too much.
