POWER CONVERTER AND METHOD OF ASSEMBLING THE SAME

摘要

A power converter (114) includes a plurality of power conversion modules (152/154). At least one power conversion module includes a plurality of power conversion devices (S1/S2/S3/S4/D1/D2/D3/D4/D5/D6) defining a three-level bridge (200). A first power conversion module (152/154) includes four terminals including one of a positive terminal (T1) and a negative terminal (T5), an output terminal (T3/T7), a first neutral terminal (T2/T6), and a second neutral terminal (T4/T8). The first neutral terminal is coupled to a direct current (DC) link (136) and the second neutral terminal is coupled to a second power conversion module (154/152).
