Abstract:
An integrated magnetic structure, comprising:first and second magnetic flux circuits in a single structure of high-permeability soft magnetic material;a first winding coupled to apply magnetomotive force to said first flux circuit, and a second winding coupled to apply magnetomotive force to said second flux circuit; said first and second windings each having a greater width than height;wherein said first flux circuit includes botha first portion of said structure, and alsoa first air leakage path whichshunts flux around a second portion of said structure, and has a reluctance which is less than the reluctance of said second portion of said structure;wherein said second flux circuit includes bothsaid second portion of said structure, and alsoa second air leakage path whichshunts flux around said first portion of said structure, and has a reluctance which is less than the reluctance of said first portion of said structure.
