Abstract

Predetermination of losses and inductance values in the design phase, is necessary for the development of high-performance magnetic components for power electronics. Numerical modeling, based on the finite element method (FEM) can be used to determine the characteristics of a particular component with a complex geometry in high frequency (HF). These models are very accurate but the computation time required is high compared to analytical models. The model order reduction (MOR) methods can be applied to reduce the computation time while maintaining high accuracy. Nowadays, the proper orthogonal decomposition (POD) is the most popular of MOR approaches. This technique has been applied to study problems in many fields of engineering. In this paper, the POD method is developed to solve magneto-harmonic problems in order to study a HF planar magnetic inductor.
