三相电流型PWM整流器的控制方法发展综述

Development Review of Control Methods for Three-Phase Current-Source PWM Rectifiers

概括了三相电流型PWM整流器(CSR)控制方法的发展历史与现状,分析了这些方法的工作原理及优缺点;针对消除由电压不平衡产生的低次非特征谐波,介绍了加大滤波器尺寸、前馈补偿、反馈控制3种不平衡控制方法的特点;指出了当前三相CSR控制方法存在的问题及其控制方法的发展趋势。

This paper summarizes the development history and current situation of the control methods for three-phase current-source PWM rectifiers（CSR） , and analyzes their working principles, advantages and disadvantages. In order to eliminate the low-time non-characteristic harmonics caused by the voltage unbalance, the features of the three un- balance control methods are introduced, including filter size increment, feed-forward compensation and feedback con- trol. Finally, the existing problems and the future development trends of three-phase CSR control methods are pointed out.
