摘要:本文选择最有代表性的三相输入、三相输出交一交矩阵变换器为研究对象,在分析三相-三相矩阵变换器数学模型的基础上,给出了基于常用空间矢量脉宽调制策略的矩阵变换器调制模型和调制策略,并用Matlab Simulink建立了空间矢量调制的矩阵变换器仿真模型,给出了仿真实验结果。实验结果证实了所提出的空间矢量脉宽调制控制算法的正确性和可实现性。
叙词:矩阵变换器 数学模型 空间矢量脉宽调制 Abstract:Abstract: The article takes the most DC-DC matrix convertor with 3 phase input and 3-phase output as a sample. Following the analysis of mathematical model of matrix convertor with 3-phase input and 3-phase output, the article provides modulation model and modulation strategies of matrix convertor based on the common strategy of space vector pulse width modulation(SVPWM). Matrix convertor simulation model is set up using Matlab Simulink, and results are provided. Experiments show tha the SVPWM control arithmetic is right and applicable. Keyword:Matrix convertor, Mathematical model, Space vector pulse width modulation
