dc.description.abstractUsing ferrite magnetic cores improves the efficiency of IPT and magnetic resonance based IPT systems, and can reduce unwanted stray magnetic radiation in addition to improving coupling efficiency. Performance of different ferrite geometries and various winding configurations are explored and their performance is studied using JMAG® FEA analysis. From the analysis and the experimental results, it is seen that the U-U core based ferrite geometry system with windings placed close to the air gap provides the most efficient coupling in larger airgap WRIPT applications. A 1.0 kW, 10 cm prototype is developed and experimental results are presented for various operating conditions. Electrical model for this novel WRIPT system is developed and the simulation results very closely match with experimental results. It is seen that the designed system can transfer power with 94.7% DC to DC efficiency over 10 cm airgap. It is also experimentally verified that this system operates with reduced magnetic radiation without an extra shielding design. Various control methods are presented to achieve required system voltage gain for charging an industrial electric vehicle (IEV) with 48 VDC battery pack from a 400 VDC DC link input.en
