Abstract
As ferrite have simultaneously non-negligible permeability, permittivity and conductivity, the magnetic behaviour of ferrite cores is frequency dependent. This article presents a method to predict the complex permeance of ferrite E- or U-cores including electromagnetic resonance. The cores are decomposed into basic segments in which Maxwell equations are solved analytically to obtain a network of frequency-dependent permeances or reluctances. Show more
