摘　　要：首先,介绍了基于高频链交流电流母线分布式电源系统的原理,这种系统除具有一般分布式电源系统的优点之外,还具有很好的负载扩展特性、较高的电气隔离特性等优点;然后,基于该原理设计了一种能够提供脉冲宽度不变,幅值可调的高频交流电流母线电源;分析了这种电源的工作过程。实验样机成功地应用在10 kV固态短路限流器中。First of all, the principle of the high-frequency AC current bus distributed power supply system, which has the characteristics of good load expansibility and Isolation of high voltage is introduced. Then, based on the principle, a novel topology of DC power supply with multiple and isolated output is presented and the working stage is analyzed in detail. A prototype has been used in solid state fault limiter with 10 kV voltage successfully.
