Abstract

This invention disclosed the Boost-Flyback DC/DC converter of a coordinated membrane switch circuit. The membrane switch circuit comprises the first switch device paralleled to the first auxiliary capacitor that connects the first auxiliary converter connected to a power-storing capacitor. There is at least one inductor whose input is connected to a power source and whose output is series-connected to the first switch device that is connected to the power source. There is the second switch device connected in parallel to the second auxiliary capacitor that is series-connected to the output of the inductor. There is the third switch device connected in parallel to the third auxiliary capacitor. The third switch device and the second switch device are connected to the second auxiliary converter. There is an isolated converter whose primary side is connected to the first switch device, the second switch device, the third switch device, the first auxiliary converter, and the second auxiliary converter, so that all the switch devices can be ON when the current is zero and can be OFF when the voltage is zero.
