摘要
针对矩阵变换器共模电压产生的机理及其抑制原则,分析了共模电压瞬时值的大小,波形及其谐波频谱,得出了矩阵变换器共模电压的本质特征,并对SPWM控制策略不同开关状态下的共模电压进行了理论分析及仿真.
According to the mechanism of CMV(Common Mode Voltage) generated by MC(Matrix Converter) and the restraining principle,the magnitude,waveforms and harmonic spectrum of CMV were investigated in details,and the essences of CMV are presented.CMV of different switch states of SPWM is analyzed and simulated.
