摘　　要：分析了多个6脉波可控整流电源并联工作时,输出电流稳定性和均流系数与主电路及调节器拓扑的关系,获得了针对每个6脉波可控整流单元使用一个闭环调节器的控制电路拓扑,可保证多个并联的6脉波可控整流单元中的每个均输出基本相同的电流,具有很好的均流效果,但牺牲了输出直流电压的平滑性,而采用总电流作为反馈的控制策略,可保证稳流精度,但难以保证各并联6脉波可控单元的均流效果。The multiple 6 pulse controlled rectifier power supply in parallel at work, the relationship between the out- put current stability,flow coefficient and the topology of the main circuit and regulator are analyzed.The control circuit topology has a closed-loop regulator for each 6 pulse wave controlled rectifier unit and can ensure that each out-put current of basically the same and very good flow effect.However, it lose the smoothness of the output direct current voltage, the control strategy is used for total current feedback signal, it can ensure the precision of steady current, but it is difficult to ensure the current-sharing effect of parallel type 6 pulse control unit.
