Control Method for Multi Power Supplies Interface System Using Regenerative Snubber

Abstract

This paper proposes a novel control method for multi power supplies interface system using an indirect matrix converter. This system is constructed based on an indirect matrix converter, which does not have a large energy buffer such as an electrolytic capacitor. A snubber circuit of the indirect matrix converter is used to interface with a DC power supply. In addition, the proposed control method is based on an indirect control method with a space vector modulation. Therefore the proposed method can be easily used to achieve zero current switching in the rectifier stage.
This paper describes the multi power supplies interface system using an indirect matrix converter and its control method. Moreover, in this paper, the control range of the output voltage is analyzed. The validity of the proposed system is confirmed by the experimental results.
