带平衡电抗器双反星形可控整流电路的深入理解和分析

Analysis of dual reverse-stars type silicon-controlled rectifier equipped with balanced reactance

针对大功率双反星形可控整流电路的教学中,学生在某些知识点的理解上存在的困难和共性问题,搭建了仿真实验电路,利用仿真电路详细讲授带平衡电抗器的双反星形可控整流电路的工作原理,分析该电路中平衡电抗器的作用,然后将此电路拓扑与三相全控桥电路进行比对,并给出了仿真结果。理论分析和仿真实验验证的结合,使学生对该知识点的理解和掌握更为透彻。

During several years of teaching on power electronics for undergraduate students,some common misunderstanding problems have been found,however,the textbooks do not provide detailed explanation and verification on this point.This paper illustrates the operation principle of the dual reverse-stars type siliconcontrolled rectifier（RSTSC）equipped with balanced reactance.Analysis of the balanced reactor in the circuit is also illustrated.Moreover,to demonstrate the merits of RSTSC,Comparison results with the three-phase fully controlled bridge circuit are provided by simulation verifications,which would be beneficial for the students to deeply grasp the knowledge points.
