Abstract：The input currents of Vienna rectifier with Space-Vector Modulation are distorted seriously around zero-crossing point. In this paper, the cause of current distortion around zero-crossing point is analyzed in the two-channel interleaved Vienna Rectifier System with dual-loop control under d-q rotation frame. Then, an improved space vector modulation method for Vienna rectifier is proposed. The proposed method is easy to implement without extra calculation. To avoid input current distortion, the redundant vector is rearranged in particular sectors, where the input current is around zero-crossing point. In addition, the application range of the proposed method is analyzed, and the performance of the method such as mid-point current and current ripple is analyzed compared with the traditional SVM. Finally, the performance of the proposed method is verified by simulation and experiment.
