In this dissertation, a core design is proposed to minimize the core loss of a high-power wireless charging system (WCS). The core-loss characteristics are investigated through finite element analysis (FEA). Compared to the traditional uniform thickness core, in the proposed core geometry, the core thickness in the pad is considered as a design variable. An FEA-based optimization algorithm is developed for the proposed core to decrease the variation of flux density in the core by optimizing the core thickness and thus minimize the core loss. The effectiveness of the proposed design and optimization is verified for a double-D (DD) coil-based 5 kW WCS prototype. Simulation and experimental results show that the core loss in the proposed core can be reduced by up to 25% compared to the traditional core made with ferrite blocks with uniform thickness. An advanced shield design method is proposed to suppress the electromagnetic field emissions in high-power WCS. To design a low-loss highly-effective shield for the high-power circular pads, a copper shield-ring is added with the traditional aluminum shield to provide an additional degree-of-freedom to the design. The shielding-effectiveness and loss of the proposed shield-ring are investigated through FEA and tested using a 7.0 kW WCS. The simulation and experimental results show that the shield loss was reduced by 20% using a copper shield ring compared to the traditional aluminum shield and the magnetic field emission was suppressed below the limits of the International Commission on Non-Ionized Radiation Protection (ICNIRP).For the DD charging pads, a hybrid-shield is proposed combining the magnetic and conductive shielding techniques. The effectiveness of the proposed hybrid-shield was investigated through FEA and tested for a DD coil-based 11 kW WCS. The simulation and experimental results show that using the proposed hybrid-shield, the leakage magnetic field can be suppressed by up to 37% compared to a traditional aluminum shield.
