摘　　要：介绍了低压大电流整流电源的特点和组成,为了提高整流效率,应采用双反星形整流电路,介绍了此电路的工作原理。与之匹配的整流变压器有两种型式:传统的双反星带平衡电抗器整流变压器和三相5柱整流变压器,并介绍了后者的工作原理。当晶闸管双反星形整流器配置了三相5柱整流变压器,在多台并联运行时直流输出电流会发生剧烈振荡,详细分析了振荡的原因和改进的措施。The characteristic and composing of low voltage high current rectifier power supply was introduced. Usually the rectifier circuit is double star in reverse type, and its operation principle was introduced. There are two configuration types of rectifier transformer coupled the rectifier circuit; the conventional rectifier transformer of double star in reverse with balance reactor and rectifier transformer of three phases and five columnes ,the latter operation principle was introduced. The DC output current will happen acute surge when some rectifier power supplies of thyrister double star in reverse are parallel run and if they are connected to rectifier transformer of three phases and five columnes. The surge reason and improve solution was given
