INTEGRATED INDUCTOR ASSEMBLIES AND ASSOCIATED SYSTEMS AND METHODS

Abstract:

A switching power converter includes an integrated inductor assembly, a first switching stage, and a second switching stage. The integrated inductor assembly includes a magnetic core and first and second windings disposed at least partially in the magnetic core. The second winding is separated from the first winding by a separation portion of the magnetic core. The first switching stage is configured such that a first current flowing from the first switching stage to the first winding induces first magnetic flux flowing through the separation portion of the magnetic core. The second switching stage is configured such that a second current flowing from the second switching stage to the second winding induces second magnetic flux flowing through the separation portion of the magnetic core that opposes the first magnetic flux in the separation portion of the magnetic core.
