This paper presents an adapted partial element equivalent circuit (PEEC)-based methodology applied to the modeling of interconnections of power electronics devices. Although this method is already well known, the originality of this work is its use to model a device presenting an industrial complexity. To make possible this modeling, two adapted integral methods, based on two different meshings, are presented. They are dedicated respectively to the computation of parasitic inductances and capacitances and lead to an equivalent circuit of the system. From a time-domain simulation of this circuit, current and voltage sources can be extracted and used to compute the radiated near magnetic field. This approach has been applied to model a real industrial static converter via system couplings, a variable speed drive. Good agreements have been obtained between simulated and measured results on conducted and emitted electromagnetic analysis.Index Terms-Electromagnetic compatibility, fast multipole method, parasitic capacitances, parasitic elements, partial element equivalent circuit (PEEC), power electronics, power interconnections.

The radiation is, for the most part, generated by common-mode currents. This paper shows that action on layout can reduce common-mode currents effectively. Cost-effective, the common-mode current control enables the radiation level knowledge at the conception of a device. This is an important gain of time. Four Boost structures are studied in order to validate first, experimentally and second by modelling, reduction common-mode current layouts, supposed effective. The simulated models are based on the partial equivalent element circuit (PEEC) method. We show also the impact of these layout techniques on radiated perturbations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
