摘要
对直接实现式矩阵变换器在非对称输入电压条件下输出电压与输入电流的谐波问题进行了分析。提出一种改进的开关调制矩阵。通过在开关调制矩阵中引入消谐分量，消除了输出线电压与输入电流中的各次谐波。对矩阵变换器的实际应用具有一定的指导意义。
The output voltage harmonics and input current harmonics of directly realizing matrixconverter under unbalanced input voltages are analyzed. A novel modified switch modulationmatrix is proposed. By introducing harmonic eliminating components to the switch modulationmatrix, these unwanted harmonics are eliminated. This method has certain significance toguide practical applications of matrix converter.
