摘　　要：研究了一种应用于新型微波炉电源的ZVS高频变换器;基于谐振变换的交流等效电路以及微波炉负载类型,推导出准谐振电路关键部分即谐振电容和电感的值,并对电路的其他的参数进行了设计。根据所计算出的参数试制了样机,实验结果表明,所设计的变换器实现了对微波炉磁控管的软开关控制,达到了预期设计要求。A novel ZVS soft-switching high frequency converter for microwave oven has been analyzed in this paper. Considering the AC equivalent circuit for the resonant converter and the load type of microwave oven, we have deduced the values of the capacitor and the inductor of the resonant converter. Then a prototype is designed based on the calculated parameters. The result of the experiment show that soft-switching is realized successfully and the magnetron can be droved indeed.
