阐述了矩阵变换器双空间矢量调制策略的基本原理,详细分析了采用优化9段调制策略的开关转换过程及其相应的开关脉冲波形。提出了一种简单的载波实现方法,通过Matlab/Simulink软件仿真验证了调制策略及其简易实现法的正确性和可行性,对于基于DSP+CPLD的矩阵变换器样机实现有较强的指导意义。

The basic principle for a matrix converter with double SVM technique is presented in this paper. The detailed process of switches conversion and their relative pulse wave using a optimized nine-step modulation strategy is analyzed. And then a simple way for the realization of carrier waves is put forward. At last, a MC model by means of Matlab/Simulink is set up to verify the correctness and feasibility of the modulation strategy. It＇s very helpful to the realization of MC samples.
