The Realization of Matrix Converter Four-step Commutation Strategy and Matlab Simulation

矩阵式变换器换流策路的研究很广泛,基于电流方向检测的四步换流策略,以及基于电压方向检测的四步换流策略都得到了进一步的研究和应用,随着理论研究地一步步成熟,随之而产生的两步换流策略也成为研究的热点。很少有研究人员对四步换流的具体过程以及输出波形进行详细分析。本文选择两相电压输入,对基于电流方向检测的四步换流策略进行详细的分析,并在MATLAB下进行了相应的仿真,得出换流过程的输出电压和电流的波形。

the research of Matrix converter commutation strategy is extensive, the four- step commutation strategy based on the current direction detection , as well as the four- step commutation strategy based on the voltage direction detection is to be further research and application, with the theory become mature step by step, the two-step commutation strategy following it has become a research hotspot. There are few researchers who analyze the four-step commutation strategy and the output waveforms in detail. This paper selected the two phase voltage input, and analyzed a four-step commutation strategy based on current direction detection in detail, the corresponding simulation is given in MATLAB. it provide you the output voltage and current waveforms in the commutation process.
