This paper presents a trade–off study examining the impacts of modifying resonant frequency and coil current density on coil power density for a 100kW electric vehicle charging system. We find that power density can be increased significantly by moving to higher operating frequency and current density with marginal impact to overall coil–to–coil transfer efficiency. A detailed prototype model of a 150 kVA rated coil set is presented along with loss estimates from magnetic field simulations and initial test results up to 50kW.
