Misalignment Influence on Resonance Shielding in Wireless Power Transfer for Electric Vehicles

This paper presentes an analysis of the sensitivity of resonance shielding in wireless power transfer systems to lateral and longitudenal misalignments by three-dimensional finite element magnetic field simulations. The resonance shielding is implemented as inductive-capacitance pairs placed in the wireless power transfer system. In addition, the overall efficiency of the system is determined.
