Abstract
Ferrite inductors are widely used in the field of power electronics, a subject included in various curricula in the universities both at the undergraduate and postgraduate level. These inductors are difficult to model due to the wide variety of shapes, number of turns, and the nonlinear behavior of the core that exhibit saturation, hysteresis and power losses. For this reason, it is necessary to resort to numerical methods such as Finite Element Analysis. In this paper we give some guidelines and recommendations for students to correctly use Finite Element programs for modeling inductors with different shapes. We give a vision of the modeling procedure of inductors including the simplifications that students should make in the 3D inductor model to achieve convergence and the assigning of materials as well as boundary and meshing conditions. Finally, we show representative results of the procedure.
