Three-Phase Buck type Rectifier topology integrated with Current Fed Full-Bridge

A Novel Three-Phase Rectifier topology based on the integration of a Buck type Rectifier and a Current Fed Full-Bridge is proposed. The main contribution of this rectifier topology with galvanic isolation is the integration of two stages, sharing the inductor, and the reduction of the inductor current ripple. The circuit is analyzed in detail. A 2 kW demonstrator prototype has been designed, built and performed up to the nominal power.
