电力电子，buck电路，软开关，带闭环控制(Power electronics, Buck circuits, soft switching)

基于PSIM搭建的软开关电路，可以观测到每个开关过程的软开关状态，适合于研究生以上的研究使用(The soft switching circuit based on PSIM can observe the soft switching state of each switching process, which is suitable for the research and use of graduate students.)

该仿真模型能够实现零电压开关，用于研究软开关和硬开关的区别，同时可以作为buck电路运行(The simulation model can realize the zero voltage switch, which can be used to study the difference between soft switch and hard switch, and it can run as a buck circuit.)
