本文讨论了间接矩阵变换器（IMC）在电机驱动中的两种过调制控制，即方波和梯形波控制。这两种调制之间的差异进行了分析的基础上的输出-输入电压传输比（VTR），效率，和电流总谐波失真在两种负载条件下。此外，性能，然后通过实施四步换流方法在初级侧的IMC。所提出的方法的有效性将通过仿真和实验证明。实验结果表明，在异步电动机驱动系统中，方波调制的VTR可以从0.866提高到0.97，梯形波调制的VTR可以从0.92提高到0.92。
This paper discusses two overmodulation controls, namely, square wave and trapezoidal, in the indirect matrix converter (IMC) for motor drive application. The differences between these two modulations are analyzed based on the output-input voltage transfer ratio (VTR), the efficiency, and the current total harmonic distortions under two load conditions. Moreover, the performance is then improved by implementing four-step commutation methods in the primary side of the IMC. The validity of the proposed methods will be demonstrated through simulation and experimentally. The experimental results show that the VTR can be improved from 0.866 to 0.97 in the square wave modulation and 0.92 for the trapezoidal wave modulation in an induction motor drive system.
