2D Modeling Procedure to Compute the Equivalent Inductance of an Inductor with an E-Type Ferrite Core

摘要

In this paper we present a specific modeling procedure for inductors with an E-shaped ferrite core valid for calculating the inductance of an equivalent circuit from the linear operating region to the saturation region. The procedure is developed using Finite Elements in 2D. We show that using a 2D section of the real core the results are similar to the real ones, which solves the problem of convergence that appeared when E type cores were simulated in 3D, while also saving computational cost. We also discuss the effect of the gap-thickness on the magnetic properties. The data obtained by simulation are compared with experimental results.
