| 摘 要： | 针对传统ZVT-PWM变换器的辅助开关硬关断的不足,提出了一种新型PWM控制的软开关Buck变换器方案,详细介绍了该新型软开关Buck变换器的拓扑结构及工作原理,并给出了具体的设计过程。新型软开关Buck变换器的辅助电路使主开关工作在零电压状态,所有的半导体器件均工作在软开关条件下,从而减小了开关损耗。仿真结果证明了该新型软开关Buck变换器方案的有效性。

| Abstract: | To solve the shortcomings that auxiliary switch of traditional ZVT-PWM converter is hard power-off,the paper proposed a scheme of the new type of soft-switching Buck converter with PWM control,introduced topology and working principle of the new type of soft-switching Buck converter in details,and gave concrete designing process.The auxiliary circuit of the Buck converter makes main switch work in zero-voltage state,all semiconductor devices work in condition of soft-switching,which decreases losses of the switch.The simulation result proved validity of the scheme of the new type of soft-switching Buck converter. |
