Patent ID: 7289329

Claim:
A power converter, comprising: a heat sink; a magnetic core capable of producing a magnetic field; at least a first multi-layer substrate comprising at least two electrically and thermally conductive layers, and at least one electrically insulative and thermally conductive layer, each of the electrically and thermally conductive layers of the first multi-layer substrate electrically isolated from a next successive one of the electrically and thermally conductive layers by a respective one of the electrically insulative and thermally conductive layers, at least a first one of the electrically and thermally conductive layers patterned to form a first winding, at least a second one of the electrically and thermally conductive layers patterned to form a second winding, at least a portion of each of the first and the second windings disposed within the magnetic field of the magnetic core to form a planar transformer, the first multi-layer substrate thermally coupled to the heat sink; and at least a first power semiconductor device electrically coupled to one of the electrically and thermally conductive layers of the first multi-layer substrate, the first power semiconductor device electrically isolated from and thermally coupled to the heat sink via the first multi-layer substrate.
