摘　　要：分析了三相-五相矩阵变换器的两种空间矢量脉宽调制(SVPWM)调制策略。在此基础上对这两种调制策略的输出电压分别进行了傅里叶级数展开,分析了输出电压的谐波含量,并计算了两种调制策略下的畸变率;在Matlab/Simulink环境下搭建了仿真模型,对输出电压进行了快速傅里叶变换(FFT)分析。通过仿真结果与计算结果进行对比,验证了理论分析的正确性,为多相矩阵变换器的谐波分析及其滤波器的设计提供了依据。This paper conducted an analysis on two kinds of SVPWM modulation strategy of three-five phase matrix converter. And on this basis, the Fourier series expansion on the output voltages by the two different modulation strategies was conducted, the harmonic content of output voltage was analyzed, what’s more, the THD in the two modulation strategies was calculated;the simulation model was built in the environment of MATLAB/Simulink, and the FFT analysis was conducted on output voltages. By comparing the simulation results with calculation results, the correctness of the theoretical analysis is verified, which provides a basis for the harmonic analysis of multiphase and the design of filter for it.
