Patent ID: 7667441

Claim:
An inductive element for transforming or regulating voltage input from a multi-phase, interleaved power supply system into an output voltage to a load, the multi-phase, interleaved power supply system including a plurality of pulsed power sources, each of which is adapted to provide voltage to the load at a discrete phase, the inductive element comprising: a magnetic core having a distinct area of relatively-high magnetic reluctance for each power source of the plurality of pulsed power sources, each distinct area of relatively-high magnetic reluctance being spatially separated from every other distinct area of relatively-high magnetic reluctance and surrounded by areas of relatively-low magnetic reluctance; and a pair of windings for each of the plurality of pulsed power sources in the multi-phase, interleaved power supply system, each of the pair of windings including: a first, phase winding having a proximal end that is electrically coupled to an output of a respective pulsed power source and a distal end that is electrically coupled to the load, the first, phase winding being disposed about a first area of relatively-low magnetic reluctance on the magnetic core adjacent to a first distinct area of relatively-high magnetic reluctance, and a second, loop winding that is operatively coupled and proximate to the first, phase winding, the second, loop winding being electrically coupled to a closed loop and being disposed about a second area of relatively-low magnetic reluctance on the magnetic core adjacent to the first distinct area of relatively-high magnetic reluctance.
