摘　　要：不对称半桥工作在软开关模式可以减小开关损耗,提高电源的效率。分析了不对称半桥的工作原理和实现零电压开关的条件,以一台咖啡机电源为例来说明电源的设计过程。最后,实验结果证明电源在零电压开通。An asymmetrical half - bridge operation in soft switching mode can reduce switching power loss and improve the efficiency of power supply. This paper analyzes the operation principle of the asymmetrical half - bridge and the requirement of realizing ZVS in operation. An example is presented to explain the design procedure from coffee power. Finally, the experimental results are provided to verify the power zero voltage switching at turn on.
