A variety of intelligent voltage conversion chips,according to the different characteristics of each chip,is used to set up voltage conversion circuits that meet different performance requirements. The design innovations in this paper are the following two:photoelectric coupler,triode and PMOS tube are used to build the switch circuit for the implementation of the au-to quick power supply switch between adapter and battery;FPGA is used to output high and low level to control the switch cir-cuit built by PMOS tube and triode for the realization of the intelligent on-off control of the partial power supply channels. This converter has been applied to the power system of microwave detector. The testing result shows that the converter has high effi-ciency,low ripple voltage,good steady-state and dynamic response.
