一种具有大降压增益的基于矩阵的非隔离三相AC-DC整流器

This paper presents a matrix-based nonisolated three-phase ac-dc converter with a current-doubler rectifier (CDR) circuit. Buck-type rectifiers are normally used for step-down ac-to-dc conversion. However, for three-phase buck rectifiers, the lower bound of rectified dc voltage is limited as the converter is severely underutilized by operating at lower modulation index. Moreover, at lower modulati...
