This article presents a new strategy for building an equivalent RLMC circuit for electromagnetic interconnections modeling in the context of the partial element equivalent circuit (PEEC) method. The method consists in splitting the overall formulation (RLMC) into two independent formulations (RLM) and (C). Both formulations are used independently to calculate equivalent circuit elements. Once all the elements are calculated, they are merged into a global electrical model, which is solved globally with an external circuit solver. A coupling with the similar idea was presented a few years ago and showed very good performance for the modeling of electromagnetic devices where propagative effects are negligible like in power electronics applications. However, the coupling of the parasitic capacitances C with RLM circuit had to be carried out manually. Our new strategy allows us to do it in a completely automatic way.
