摘要
以单片机为控制器,采用两路DC/DC变换器(单端反激电路)并联和输出电压以及输出电流双反馈控制模拟并联供电系统。分析了并联供电系统的工作原理以及数字均流控制原理,并给出了反激变压器的设计和控制程序流程图。试验结果证明,该控制方案是有效可行的。
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.
