Abstract
An inductive device (10) comprises a magnetic core (16) including a portion of a plurality of wires (18), an electric winding (20) extending around said magnetic core, with one or more of the plurality of wires (18) at least partially encircling the electric winding (20) and having first and second end portions (26) arranged so as to form a gap (24) therebetween, and a flux coupling structure (28) disposed in a vicinity of the gap (24) so as to enhance coupling of magnetic flux between the first and second end portions (26).
