Comparing partial element equivalent circuit and finite element methods for the resonant wireless power transfer 3D modeling

In this paper, the unstructured Partial Element Equivalent Circuit (PEEC) method is applied in 3D magnetodynamics to resonant Wireless Power Transfer (WPT) coils modeling. A particular attention is paid on the coupling with circuit equations in order to model the resonant conditions at the circuit and field levels. A preliminary comparison with 3D finite element method highlights the high potential of the PEEC method for the modeling of WPT coils.
