摘 要: 研究了三相电源电压不对称及触发信号相位漂移时 ,可控整流器输出电压的谐波特征 ,利用切换函数概念建立了整流器输出与输入之间的联系 ,求出了输出电压中的非特征谐波。用大容量电力电池组作为负载进行了实验 ,得出了与理论分析一致的结果。 Harmonic characteristics of output voltage are researched for controlled rectifier with unbalance in three phase supply voltages and shift in phases of the gating signals.A switching function is introduced to describe the relationship between the input and the output of the rectifier,and the uncharateristic harmonics are gained.The same result as theoretical analysis is acquired through the experiment which takes the large capacity batteries group as load.
