Abstract：The basic principle of Vienna rectifier is introduced in this paper, and on this basis, the current zero-crossing distortion problem is analyzed. From the perspective of space vector diagram, the nature of the current zero-crossing distortion of Vienna rectifier is analyzed under the condition of unit power factor in grid side. Moreover, the control method with unit power factor in rectifier side is compared. On this basis, an improved method that can eliminate the current zero-crossing distortion and maximize the power factor in the grid side is obtained for Vienna rectifier in this paper. Finally, the control method with unit power factor in grid-side, in rectifier side and the improved control method are compared by experiments. The feasibility and superiority of the control method proposed in this paper is verified by the corresponding experimental results.
