本文提出了一种改进的空间矢量调制方法，利用旋转矢量驱动矩阵变换器，使其具有零共模电压。参考输出电压矢量由较近的旋转矢量的组合产生，以尽量减少输出失真。利用显式方程建立开关模式，使所提出的支持向量机方法能够实现输出电压矢量和输入电流相角的完全控制，并具有良好的输入/输出电流波形性能。结合理论分析，给出了实验结果，验证了所提方法的可行性。
This paper presents an enhanced space vector modulation (SVM) method to drive matrix converters (MCs) with zero common-mode voltage by using the rotating vectors, which are not used in the traditional SVM for MCs. The reference output voltage vector is generated by a combination of the closer rotating vectors in order to minimize the output distortion. Explicit equations are used to develop the switching patterns so that the proposed SVM method can achieve full control of the output voltage vector and input current phase angle with good performance of the input/output current waveforms. Together with the theoretical analysis, the experimental results are provided to validate the feasibility of the proposed method.
