Abstract

A power converter module includes a carrier board, a transformer, and an inductor. A converter and a rectifying unit are arranged on the carrier board. The transformer includes a primary winding portion and a secondary winding portion. The primary winding portion is arranged on first side of the carrier board and coupled to an output terminal of the converter. The secondary winding portion is arranged between the first side and the primary winding portion and coupled to the rectifying unit. The inductor includes an input portion and an output portion. The input portion is arranged on the first side and coupled to the rectifying unit. The secondary winding portion is implemented with a conductive plate, and the input portion and the conductive plate are integrally formed. The output portion is coupled to the input portion and arranged on the first side or a second side of the carrier board.
