Research on Bipolar Space Vector Pulse-width Modulation Strategy for Reduced Matrix Converter

精简矩阵变换器（Reduced Matrix Converter，RMC）除具有传统矩阵变换器优良网侧性能外，还克服了其电压传输比低的固有缺陷，为一种新型AC／DC功率变换器。对适用于RMC的双极性电流空间矢量调制策略进行了分析推导，搭建了一台以DSP＋CPLD为控制核心的2kW实验样机对调制策略进行了实验验证，良好的输入输出波形验证了方案的正确性和可行性，为RMC进一步工业应用奠定了基础。

Reduced matrix converter （RMC） is a kind of novel power conver, which not only owns the perferect input performance of conventional matrix converter, but also solves the problem of low voltage transfer ratio.The bipolar space vector pulse-width modulation strategy suited for RMC was analyzed and duduced.a prototype based on DSP ＋CPLD controller was built , The feasibility and validity of the proposed method has been verified by the good experimental results.This work would make the RMC be further applied in the industy.
