Abstract
A multiphase power converter includes a plurality of subconverters and a control circuit. Each subconverter has an input circuit, an output circuit, and a magnetic core coupling the input circuit to the output circuit. The magnetic core of at least one of the plurality of subconverters has a core section that is shared by the magnetic core of another one of the plurality of subconverters. The control circuit is configured to operate the input circuits of the plurality of subconverters with different phases. The magnetic cores may be cores of a transformer, a coupled inductor, etc.
