Abstract:
A planar magnetic winding structure such as a transformer or inductor having an air gap in the core has a 'keep away' region of 2 to 3 times the gap height in which there are no windings, reducing high frequency winding losses by 35 percent or more, without appreciable increases in low frequency winding losses. Such structures are useful, for example, in electronic ballasts for the lighting industry.
