摘要
在分析三相-三相矩阵变换器数学模型的基础上,给出了基于虚拟整流器和逆变器的矩阵变换器的等效结构。在此基础上提出了基于常用空间矢量PWM策略的矩阵变换器的空间矢量PWM算法,并在MATLAB仿真环境下建立了矩阵变换器的仿真模型,给出了仿真实验结果。实验结果证实了所提出的空间矢量PWM策略正确性和可实现性。
On the basis of analyzing the mathematical model of three-phase to three-phase matrix converter,the equivalent structure of matrix converter is given based on the virtual rectifier and inverter.The space vector PWM arithmetic of matrix converter is proposed based on the conventional space vector PWM.The simulation model of matrix converter is built under MATLAB and simulation results are showed.The results verify that the proposed space vector strategy is right and realizable.
