摘　　要：移相整流变压器是多重化晶闸管整流器的重要组成部分,研究其原副边的电流关系是对整流系统进行定量分析的基础。本文作者根据瞬时功率平衡概念,推导出移相整流变压器原副边电流之间的一般关系式,表明移相整流变压器原副边的电流关系只与变压器的变比和移相角相关。对曲折移相方式中几种移相角度的仿真结果验证了原副边电流关系式的正确性。最后指出这种关系不仅适用于移相整流变压器,也适用于一般电力变压器。Phase-shift rectifier transformer is an important part of multiplex thyristor rectifi er.Studying the current relationship of primary and secondary sides is the basis of quantitative analysis of rectifier system.Based on the concept of instantaneous power balance,the general relation between primary current and secondary current of phaseshifting rectifier transformer is derived in this paper.It is shown that the current relation between primary current and secondary current of the phase-shifting rectifier transformer is only related to the transformer ratio and phase shift angle.The simulation results of several phase shift angles in the zigzagging mode verify the correctness of the current relation.Finally,it is pointed out that this relation is applicable not only to phase-shifting rectifier transformers,but also to general power transformers.
