基于单级AC/DC变换器的减少组件数量的半模块化固态变压器

This article proposes a novel semimodular three-phase ac/dc structure for modular solid-state transformers. The proposed system employs single-stage indirect matrix-based ac/dc converters. A single full-bridge rectifier is used for each phase of the medium voltage grid so that each ac/dc module does not need a voltage rectifier. As a result, the number of semiconductor devices in the proposed syst...
