| Abstract: | This parallel power supply system was proposed and designed with mieroprogrammed control unit （MCU） ,using flybaek circuits in parallel and the output voltage and output current dual feedback control to build and simulate power supply system in parallel. The paper analyed the operation principle and digital control method of power supply system in parallel, and gave the design of the flyback transformer and the control program. A prototype was developed and the experiments show the control scheme is effective. |
