一种采用多输出桥式功率变换器的变频微波炉电源
摘要：
本发明涉及一种采用多输出桥式功率变换器的变频微波炉电源，包括整流电路和桥式功率变换器，所述整流电路的输入端与市电相连，输出端与桥式功率变换器的输入端相连，所述桥式功率变换器带有两路输出，一组由灯丝电源绕组，经电感，向磁控管灯丝供电；另一组由阳极电源绕组经改进型倍压整流电路，向磁控管阳极供电。本发明能够实现灯丝电压和阳极电压独立可调。
摘要（英）：

The invention relates to an inverter microwave oven power supply adopting a multi-output bridge-type power converter. The inverter microwave oven power supply adopting the multiple output bridge-type power converter comprises a rectifying circuit and a bridge-type power converter, an input end of the rectifying circuit is connected with an electric supply, an output end of the rectifying circuit is connected with an input end of the bridge type power converter which carries two lines of outputs, one set of the outputs supplies electricity for a magnetron filament by adopting filament power supply winding through inductance; the other set of the outputs supplies electricity for a magnetron anode by adopting anode supply winding through an improved voltage doubling rectifying circuit. By means of the inverter microwave oven power supply adopting the multi-output bridge-type power converter, the independent adjustment of the filament voltage and the anode voltage can be achieved.
