由于相间Transformer的激磁电感有限，12脉波整流器的六脉波组之间的触发角不平衡导致电流不平衡。电流不平衡的量受到六脉冲组的负载调节的限制。本文提出了一种定量分析的这种影响和其他人，基于适当的模型的系统。方程预测稳态电流的变化和瞬态行为，使用平均模型。一个分段线性模型的系统被用来验证和扩展的结果，通过计算机仿真。结果被标准化，使它们对设计目的有用。<<ETX>>
Firing angle imbalance between six-pulse groups of a 12-pulse rectifier leads to current imbalance, due to the finite magnetizing inductance of the interphase transformer. The amount of current imbalance is limited by the load regulation of the six-pulse groups. This paper presents a quantitative analysis of this effect and others, based on appropriate models of the system. Equations are developed which predict steady-state current shifts and transient behavior using an averaged model. A piecewise-linear model of the system is used to verify and extend the results via computer simulation. Results are normalized, making them useful for design purposes.<<ETX>>
