An inductor (2) having a "double-E" core (4, 6) with an air gap (16) between its center limbs. A bobbin (8) has a hollow interior in which the core's center limbs and gap are positioned, and around which a winding (12) is wound spanning the gap. The bobbin has a shoulder (10) in the region of the gap which spaces the winding from the core in that region. Fringing flux (20, 22) generated in the region of the gap is contained within the transformer and a reduction is achieved in the amount of fringing flux which intersects with the winding and generates eddy current heating and power losses. With the addition of a secondary winding (114), the inductor may form a transformer (102). |
