晶闸管电感耦合式强迫换流电路的深入理解与仿真分析

Simulation and deep understanding of thyristor based inductive coupling forced commutation circuit

针对电力电子技术本科教学过程中发现的学生在某些知识点(教材中对这些知识点未作详细说明)上存在的共性问题,该文详尽介绍了晶闸管电感耦合式强迫换流电路的工作原理,分析了该换流电路中二极管导通的临界条件,并给出了仿真结果。把理论分析和仿真实验相结合,使得让学生对该知识点的理解和掌握更为透彻。

During several years of teaching on forced commutation circuit in Power Electronics for undergraduate students ,some common misunderstanding problems have been found on the students ,however ,the textbook does not provide detailed explanation and verification on this point . This paper illustrates the operation principle of thyristor based inductive coupling forced commutation power circuit .The corresponding critical condition for the by-pass diode is analyzed ,and the simulation results for verification are also provided ,which would be beneficial for the students to deeply grasp the knowledge points .
