Modulation Strategy Summary of Matrix Converter

矩阵式变换器所含开关较多,数学模型复杂,控制繁琐,因而在矩阵式变换器的实际应用中,采用适当的调制策略加以实现,这是保证系统稳定可靠运行的一个至关重要的环节。本文在矩阵式变换器拓扑结构和换流方法的基础上,详细综述了三相-三相交流矩阵式变换器的几种调制策略,最后对矩阵式变换器的调制策略进行了展望。

Matrix converter with more switch, complex mathematical model and cumbersome control, Thus in the practical application of matrix converter, Using appropriate modulation strategy to be implemented, which is a vital link to ensure that the system is stable and reliable operation. In this paper, based on the topological structure and commutation method of matrix converters, the several modulation strategies for three-phase to three-phase AC matrix converter are presented in detail. Finally, the paper looks forward to the development trends in the modulation strategy of matrix converters.
