HIGH POWER INDUCTOR AND IGNITION TRANSFORMER USING PLANAR MAGNETICS

摘要

Described are methods and systems for using a planar inductor that includes a magnetically conductive core, a first planar coil and a second planar coil. The first and second planar coils are attached to a first bridge, located about the core, and are composed of a conductive material. The first and second planar coils have at least one thermally conductive surface exposed to cooling fluid. The first planar coil, the first bridge and the second planar coil are formed from a first unitary section of conductive material. The second planar coil is positioned relative to the first planar coil in a spaced relationship, which is defined by a thickness of the first bridge. An upper surface of the first planar coil is oriented toward a lower surface of the second planar coil to define a first cooling channel between the first planar coil and the second planar coil.
