已经发现了一种矩阵变换器的控制方法，以将四线制三相电压转换为三线制单相电压（单相MC），其取代微电网用户侧的Transformer [1]。在单相MC中，由于输入和输出滤波器导致线电流流动，因此其负载电压中会发生电压降和相移。因此，我们提出了单相MC [2] [3]的负载电压控制方法，以补偿它们，为用户侧提供对称的两相交流负载电压。然而，当输出负载变为无负载时，单相MC的输出侧变成仅剩下LC滤波器，并且引起谐振，但是不能通过传统的负载电压控制来抑制谐振。本文提出了一种针对单相MC的阻尼控制方法，并通过仿真验证了该方法的有效性。
A control method of a Matrix Converter to convert from four-wired three-phase voltages to three-wired single-phase voltages (single-phase MC) which replaces transformer in consumer side on micro-grid has been found [1]. In the single-phase MC, voltage drop and phase shift in its load voltage occur because the line current flows due to the input and output filters. So we proposed the load voltage control method for the single-phase MC [2] [3] to compensate them to supply symmetrical two-phase AC load voltages for consumer side. However, when the output load changed to no-load, the output side of the single-phase MC became only LC filter left and resonance was caused but it could not be suppressed by the conventional load voltage control. So we should propose a new method to suppress it. In this paper a damping control method for the single-phase MC is proposed, and the effectiveness of the proposed method is verified by simulation results.
