Abstract
The trend towards planar shapes for electromagnetic components in high-frequency power converters presents difficulties for the design of inductors that operate at frequencies in the megahertz range. Two existing and two improved inductor design concepts are studied, and it is shown how the internal and external leakage fields are affected by them. Flux plots are presented to illustrate the patterns of these fields and theoretical and experimental results for winding losses are given
