Wireless dynamic charging (WDC), while the vehicle is in motion, perceived as an enabling technology to mass roll-out of electric vehicles. High output power with minimized pulsation (ripple) is the key-success for such a technology. This paper is presenting a parametric-analysis procedure, aiming at providing design tools for coupler coils of three-phase WDC to achieve specific efficiency and cost requirement. A general design procedure is proposed for a high power WDC system supported by extensive analytical analysis and finite-element analysis (FEA) simulations for wide ranges of transmitter and receiver dimensions, constrained by the stray fields level limitation. Subsequently, other parameters such as the resonant tank are then recalculated to satisfy the system specification. The calculated efficiency is derived according to the loss model of every single component while a cost model is utilized to determine the associated cost, where the trade-off between efficiency and cost is obtained by parametric-analysis results. The viability of the proposed procedure is experimentally validated using a 3-kW WDC prototype. The practical results show that the efficiency of 88.2% is achievable with an air gap of 15 cm and a normalized cost factor of 0.845.
