摘要
在非对称输入电压情况下 ,矩阵变换器基于空间矢量控制法的输出电压和输入电流中都将含有谐波分量。通过采用时变调制比的方法 ,可以消除不对称输入电压的影响 。
Under the unbalanced input voltage,the output voltage and input current of matrix converter which is based on the space vector modulation contain the harmonics.By using the time variant modulation ratio method,the harmonics can be eliminated and a sinusoidal and balanced output voltage or input current is obtained.
