✦ Synopsis

The trend towards plana'r shapes for electromagnetic components in high frequency power converters presents difficulties for the design of inductors that operate at frequencies in the MHz range. The paper studies two existing and two improved inductor design concepts and shows 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.
