关于矩阵变换器的综述

Summarize about Matrix Converter

由于矩阵变换器没有大型的储能电路,输入输出功率因素可调,谐波含量小且大部分为容易滤除的高次谐波,其最大好处还在于能够直接将交流输入变成可调的交流输出,没有中间直流储能系统,体积大大缩小,安然方便,并且由于去掉了大容量的电解电容使得其故障率能够明显的减少。主要论述了矩阵变换器的原理与结构重点,讲述了矩阵变换器的空间矢量控制方法,以及四步换流的安全换流方法,并对现阶段矩阵变换器的主要研究方向做了简要的介绍。

Matrix converter has many advantages that having no huge storage circuit, adjustable input and output power factors, low harmonic component and mostly is easily eliminated high frequency component. The outstanding merit of matrix converter is it can realize the transform from AC to AC straightway and its output is adjustable without middle DC storage system. Thus, the main circuit is simplified and the volume is decreased. This is helpful for volume restriction and reliability. Th＇!s paper analyzes the principle and construction of matrix converter. It emphasis on the control method based on space vector and four-step safety commutation measure. It introduces nowadays the main research about matrix converter in brief.
