摘要
分析了基于空间矢量调制矩阵变换器在输入电压非对称时的输出电压谐波问题,提出了一种有效的改进措施,通过在虚拟整流空间矢量调制矢量中注入负序分量,使得输出电压的谐波含量和不对称性均得到明显改善。通过数值仿真验证了所提方法的正确性。
The output voltage waveforms of the matrix converter which is based on the space vector modulation are analyzed under the unbalanced input voltages. An effective modified method is proposed. The output voltage waveforms are improved obviously by adding negative consequence components into modulation vector of fictitious rectifier. The validity of this method is verified by numerical simulation.
