摘　　要：针对目前DC/DC变换器多数采用单片机作为控制芯片,控制效果不好的问题,提出了一款基于DSP的推挽正激DC/DC变换器,给出了其控制电路以及保护电路。实验数据以及图形表明该DC/DC变换器,具有变换效率高,输出电压稳定、动态响应速度快、发热量小等优点。The current DC/DC converter mostly use single chip as control chip, which do not have excellent control effect. A push-pull forward DC/DC converter system was designed based on DSP. The control circuit and protection circuit was introduced. Through analysis of waveforms and dates, this converter has the advantages of high conversion efficiency, stable output voltage, fast dynamic responding, small calorific capacity, and etc.
