Previous methods for calculating power loss in litz-wire windings usually assume very fine
strands such that the diameter of strands is much smaller than skin depth. In this paper, we …

Design optimisation techniques for power electronic converters have been the subject of
numerous research studies for the past 15 years. Accurate modelling is the most important …

A general approach for the frequency-domain homogenization of multiturn windings in two-
