提出了一种基于有源缓冲器的单相-三相功率变换器的空间矢量调制方案。提出的电路是基于间接矩阵变换器的控制理论，它可以成功地减少直流环节部分的平滑电容器的体积。所提出的电路需要同时控制输出电压和缓冲电流。为了降低输出电压和输入电流的谐波，提出了一种空间矢量调制方案。在本文中，所提出的方法的基本操作是由实验结果证实。基波分量频率附近的输入电流THD和输出电流THD分别为3.34%和6.65%。此外，由于开关波形变为对称形状，输入滤波器中的电容电流THD和低于15 kHz开关频率的输出电压THD分别改善了10%和17%。这些结果证实了所提出的方法的有效性。
This paper proposes a space vector modulation scheme for a new single phase to three phase power converter that using an active buffer. The proposed circuit is based on the control theory of an indirect matrix converter which can successfully reduce the volume of the smoothing capacitor in the DC link part. The proposed circuit needs to control the output voltage and the buffer current at the same time. In order to reduce the output voltage and the input current harmonics, a space vector modulation scheme is proposed. In this paper, the basic operation of the proposed method is confirmed by experimental results. The input current THD and the output current THD around the fundamental component frequency are 3.34% and 6.65%, respectively. Moreover the capacitor current THD in the input filter and the output voltage THD that is below than 15 kHz switching frequency are improved by 10% and 17% because the switching waveforms becomes symmetrical shape. The validity of the proposed method is confirmed with these results.
