摘　　要：设计了一种带负载前馈、限流功能的1kW特种电源,主要用于为户外一直处于快速变化的负载供电,比如车载空调、车载冰箱负载。文章在给出拓扑结构的基础上,分析了其工作原理,给出主要外围器件参数的计算,并搭建出了实验平台,实验结果表明,采用该特种电源工作稳定可靠,能很好地抵抗负载的突变,维持输出电压稳定,具有良好的工作特性,能有效满足工作要求。This paper designed a lkW specialty power supply with load feed-forward and current limiting,the power of is mainly used for outdoor load which in a rapidly changing such as in-car air conditioner and in-car refrigerator load. Gives the main circuit topology, introduced the working principle and the main parameters calculation of the peripheral circuit, and build out the experimental platform, experimental results show that this special power supply stable and reliable a, nd can be very good resistance to the mutation load to maintain output voltage stability, has good working characteristics, can effectively meet the job requirements.
