Finite Element Simulation of Electromagnetic Properties of Ferrite Material

摘要

As the inductance of magnetic cores is the most important parameter for their service performance. Four coupling models of EE-type ferrite cores are established to analyze the relationship between surface quality and the inductance of ferrite cores. Besides, 3D FEM simulation of different models is made by ANSOFT MAXWELL software. The results show that the surface quality has a direct influence on the service performance of ferrite devices.
