A Grad-Div Regularized Electromagneto-Quasistatic Field Formulation

Marvin-Lucas Henkel, Fotios Kasolis, Markus Clemens

University of Wuppertal, Germany

Electromagneto-quasistatic field formulations capture resitive, capacitive and inductive effects, while neglecting wave propagation. These formulation are commonly based on the vector magnetic and scalar electric potentials A and φ, respectively, and they require gauging in order to be uniquely solvable. To this end, a finite-element discrete grad-div gauged formulation is presented and numerically verified.

Analysis of electro-thermal homogenisation for the fast and accurate modelling of windings in power electronics magnetic components

This paper deals with the electro-thermal characterisation of multi-turn windings in the magnetic components of power electronics (PE) converters (inductors and transformers). The ever higher frequencies and smaller PE components demand the fast and accurate power loss computation for an optimal design accounting for severe electro-thermal constraints. Homogenisation techniques prove indispensable. Works on both electromagnetic and thermal homogenisation exist but mainly consider both physics independently. We aim at studying the interaction of the strongly coupled systems when applying homogenisation techniques.
