Magnetic field analysis of ferrite core by using Chua-type-model

This paper presents magnetic flux distribution and iron loss distribution in ferrite cores under pulse excitation by using the finite element method. The authors propose the numerical analysis method considering the frequency dependence of magnetic characteristics in a ferrite core. It is difficult to consider the magnetic characteristics in numerical analysis under the pulse excitation. The magnetic characteristics under the pulse excitation are examined by using the magnetic characteristics of each frequency component after Fourier expansion.
