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。
In this paper, a novel full-bridge quasi-resonant switching power supply is designed, which is based on the phase-shifted full-bridge ZVS converter. The auxiliary resonant network is added to make it realize the zero-voltage switching of the hysteresis arm of the full-bridge converter and reduce the power loss. Improve the switching power supply efficiency.
