摘　　要：为了解决传统微波炉电源系统采用普通升压变压器体积大,重量重的问题,提出了一种新型的微波炉磁控管电源系统。通过对微波磁控管电源系统的研究,采用了将变频技术应用于电源系统中。工频电源经滤波后,进入电路系统,转换成高频电源,供给微波能量产生电路,使输出功率随电源系统的变化而改变。In order to solve the problem of traditional microwave power supply system, a new type of power supply system is presented for microwave oven magnetron. The ordinary transformers which is used in traditional microwave power have heavy weight and large in size. Through the analysis on the microwave magnetron inverter technology is applied in power system. Common power supply entered circuit after filtered, then converted to high-frequency power. The converted power will be supplied to magnetron, then the output power will he changed with the power supply.
