一种具有复位绕组和辅助有源钳位电路的宽输入电压范围双开关正激变换器

In this study, a two-switch forward converter with reset winding and an auxiliary active-clamp circuit for a wide input voltage range are proposed. The proposed converter offers simple reset scheme through reset winding, while retaining the reduced voltage stress on the switches. Hence, the operating duty ratio can be extended. Furthermore, it can also attain zero-voltage switching (ZVS) through t...
