Coil Power Density Optimization and Trade-off Study for a 100kW Electric Vehicle IPT Wireless Charging System
This paper presents a trade-off study examining the impacts of modifying resonant frequency and coil current density on coil power density for a 100 kW 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 50 kW.
