Abstract

A coiled power device including a magnetic core including a first leg and a second leg which are parallel to each other, the device including a first coil and a second coil to generate mutual inductance between the coils, the first coil including a first winding of conducting wires around the first leg and a second winding of conducting wires around the second leg, the second coil including at least a third winding of conducting wires around the second leg and a fourth winding of conducting wires around the first leg, the first winding and the fourth winding covering the same portion of the first leg to limit leakage inductance of the coiled power device.
