Abstract :
In this paper we propose a modeling procedure and the design criterion for the simulation in 2D of an inductor with a POT type ferrite core. The procedure is capable of reproducing the nonlinear magnetic flux-current curve and the corresponding inductance-current curve in the ferrite´s complete working range, from the linear to the saturation region. It also reproduces the effect of different air-gap thickness on these curves. The Finite Element simulations are carried out in 2D with the advantages of considerable reduction of the computational cost as well as the ability to achieve convergence. The validation is made for the P22/13 soft ferrite core comparing the results obtained by 2D and 3D simulations with experimental measurements.
