In this paper, the recently developed artificial material single layer (AMSL) method is applied to model a conductive shield for wireless power transfer (WPT) systems. This method is very efficient in the simulation of a complex setup, such as that occurring in the analysis of the magnetic field produced by a WPT system installed in an electrical vehicle (EV). In this application, a critical issue is the efficient and accurate modeling of conductive shields to evaluate the near field magnetic field. To this aim, the AMSL method permits a significant reduction of the shield domain discretization and, therefore, of the computational time without altering the model physical geometry. A comparison of the AMSL with the traditional FEM solution is carried out showing very good results.

Abstract
In this paper, the recently developed artificial material single layer (AMSL) method is applied to model a conductive shield for wireless power transfer (WPT) systems. This method is very efficient in the simulation of a complex setup, such as that occurring in the analysis of the magnetic field produced by a WPT system installed in an electrical vehicle (EV). In this application, a critical issue is the efficient and accurate modeling of conductive shields to evaluate the near field magnetic field. To this aim, the AMSL method permits a significant reduction of the shield domain discretization and, therefore, of the computational time without altering the model physical geometry. A comparison of the AMSL with the traditional FEM solution is carried out showing very good results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
