摘　　要：提出了一种基于模块串联的适用于高压输入(1 kV以上)的DC/DC小功率变流器拓扑,分析了其均压均流原理,讨论了元器件参数对均压均流的影响。最后进行了仿真和实验,并对其结果进行了分析。A new topology of small power DC/DC converter with high input voltage is proposed. The proposed topology is based on serialization of basic modules. The circuh can balance the capacitor voltage and the output current automatically, and its principle is analysed in detail. The influence of component parameter on vohage and current balancing is also discussed. The simulation and experimental results are presented at the end.
