一种新颖全桥PWM准谐振开关电源设计

A Novel Full-bridge PWM Quasi-resonant Switching Power Supply Design

本文设计了一种新颖的全桥准谐振开关电源,在移相全桥ZVS变换器的基础上增添辅助谐振网络,使其能顺利实现全桥变换器滞后臂的零电压开关,减少功率损耗,提高开关电源效率。

This paper designs a novel full-bridge quasi-resonant switching power supply, on the basis of the phase shifting full-bridge ZVS converter adds auxiliary resonant network, make its can the smooth realization of full-bridge converter lagging area zero voltage switch, reduce the power loss, improve the efficiency of switching power supply.
