<p>A magnetic device (500) comprises: (1) a first core-portion (520) composed of a magnetic material and having first and second legs (535,540) associated therewith, the first leg having a first end face and a predetermined first cross-sectional area, the second leg having a second end face and a predetermined second cross-sectional area different from the first cross-sectional area, (2) a winding assembly (565) having first and second windings associated therewith and disposed about first and second winding apertures, respectively, the first and second legs passing through the first and second winding apertures, respectively, to couple the first and second windings magnetically to the first and second legs, respectively, (3) a second core-portion (530) composed of the magnetic material and adapted to mate with the first and second legs of the first core-portion (520), and (4) an interstitial non-magnetic material (570,580) of a predetermined uniform thickness disposed on the first and second end faces and joining the first and second core-portions to form a core for the magnetic device, the non-magnetic material forming a uniform air gap in the first and second legs. <IMAGE></p> |
