有源钳位电路主管不能实现零电压原因分析与解决方案

The Reasons and Solutions of the Active Clamp Circuit Main Switch Can't Achieve ZVS

基于升压式有源钳位电路,原理性分析有源钳位电路主开关管不能实现零电压开通的原因,提出两种有源钳位电路实现零电压的解决方案,解决了有源钳位电路不能实现零电压的故障,降低开关管的损耗和功耗,提高开关电源的效率和寿命。

Based on Boost active clamp circuit, this design analysis the reasons of theoretical analysis on the active clamp circuit main switch can not achieve zero-voltage turn causes, proposed two active clamp circuit to achieve zero-voltage solutions to solve the active clamp bit circuit can not achieve zero-voltage fault, reducing switch loss and power consumption and improve the efficiency and lifetime of the switching power supply
