Integrated magnetic assembly for a multiphase DC-to-DC power converter

Abstract

An integrated magnetic assembly for a DC-to-DC power converter is disclosed. The integrated magnetic assembly is configured to be electrically connectable to a switching structure and a rectification structure of the DC-to-DC power converter. The integrated magnetic assembly comprises (i) a soft-magnetic core substructure, comprising a plurality of legs and two yoke structures, where the plurality of legs are arranged parallel to one another between the two yoke structures and the two yoke structures are arranged parallel to one another, the plurality of legs comprise at least four winding legs, and (ii) a winding structure wound around the at least four winding legs, comprising a primary transformer winding structure, a secondary transformer winding structure and a choke winding structure, the choke winding structure being electrically connected to at least one of the primary transformer winding structure and the secondary transformer winding structure.
