矩陣式變換器的調制策略綜述

摘要：矩陣式變換器所含開關較多，數學模型復雜，控制繁瑣，因而在矩陣式變換器的實際應用中，采用適當的調制策略加以實現，這是保證系統穩定可靠運行的一個至關重要的環節。本文在矩陣式變換器拓撲結構和換流方法的基礎上，詳細綜述了三相-三相交流矩陣式變換器的幾種調制策略，最后對矩陣式變換器的調制策略進行了展望。 Abstract： 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.
