摘 要: 基于双空间矢量调制的矩阵变换器具有输入功率因数高、输入电流波形好等一系列优点,已成为交-交变换器研究中最有潜力在实际生产中运用的理想变换器。首先分析了空间矢量调制的基本原理,探讨了降低开关损耗的优化调制策略,然后利用Matlab/Simulink仿真工具建立了矩阵变换器的仿真模型。仿真结果验证了双空间矢量调制策略的正确性,为后续试验研究提供了依据。 The matrix converter based on double space-vector modulation has a series advantages, such as high input power factor, wonderful wave of input current and so on. It has been the ideal converter for the application in actual yield. In this paper, the fundamental theory of space-vector modulation is analyzed, the method of reducing switching loss is discussed, and a simulation model of matrix converter using MATLAB/Simulink is set up. The result of simulation proves the correctness of control strategy, and also provides basis for the experiments behind.
