摘要: The aim of this paper is to present analytical solutions for eddy current losses in foil windings gapped inductors and additional inductance because the fringing field path by using Fourier expansion space. This allows avoiding well-known disadvantages numerical calculations such as long computation times, difficult geometry modelling, complex parameterisation.
