摘要
介绍了一种双管正激变换器的初级箝位电路。该电路可以减少次级续流二极管的电压尖峰,并实现开关的ZCS开通和ZVS关断。采用该技术研制成功了3kW并-串型双管正激组合变换器。
A twotransistor forward converter with a clamping circuit connected in the primary side of transformer is proposed.This clamping circuit will reduce the voltage overshoot of the output freewheeling diode.Moreover the switching devices are turnedon with zero current switching and turnedoff with zero voltage switching.A 3 kW parallelserial combined twotransistor forward converter is developed.
