A Single-to-Three-Phase 12-Switch ACDCAC Converter

This article proposes a new single-to-three-phase converter composed by two three-leg converters. The proposed converter is an alternative to cope with the single-phase-to-three-phase asymmetry, since it guarantees a reduction in the input current by the rectifier circuit. The reduced component count is another advantage of proposed converter compared with the other solutions presented in the literature. Therefore, the proposed configuration is a good alternative to solve the problem found in remote (or rural) applications, where only a single-phase grid is available and there is a demand to supply three-phase loads. The overall control strategy for providing dc-link voltage control, grid current control, and pulsewidth modulation generation are presented. Experimental results are presented as well, in different scenarios.
