Abstract
A coupled inductor for low electromagnetic interference includes a plurality of windings and a composite magnetic core including a coupling magnetic structure formed of a first magnetic material and a leakage magnetic structure formed of a second magnetic material having a distributed gap. The coupling magnetic structure magnetically couples together the plurality of windings, and the leakage magnetic structure provides leakage magnetic flux paths for the plurality of windings.
