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.
