Electromagnetic Modeling Approaches Towards Virtual Prototyping of WBG Power Electronics

Abstract

High frequency power electronics utilizing wide-band gap semiconductor devices imposes more stringent requirements for highly accurate extraction of parasitics of power electronics systems in a wide frequency range. This paper presents the state-of-the-art modeling approaches used to predict the electromagnetic behavior of power electronic systems and components in terms of accuracy and computational cost. The potential of the Partial Element Equivalent Circuit (PEEC) technique for virtual prototyping of power electronic systems is assessed. The main advantage of this numerical technique is its capability for direct coupling between the circuit and electromagnetic domains provided by the PEEC meshing of threedimensional geometries in partial elements. The aim of this paper is to provide a more comprehensive understanding of PEEC-based modeling for power electronics packaging.

Impacts of using wide bandgap transistors on electronics and motors

“…Taking into account of the complexity of the track design, their placements and the necessity to compute the mutual inductance between all the tracks, the parasitic extraction cannot be performed analytically but can be done by a PEEC method (Kovačević-Badstübner et al , 2018). The PCB tracks R, L parasitic elements are computed.…”
