Range limitations and charging of electric vehicles (EVs) are major concerns in the modern electrified transportation systems. In this thesis, design and performance analysis of three power pads considered for EV’s wireless charging systems are carried out. In particular, a comparative performance analysis is conducted for circular and double D (DD) power pads, and a new power pad named DDC power pad is designed by combining these two power pads. Wireless charging systems of EV’s are developed, mainly based on the inductive power transfer (IPT) system where the power is transferred through electromagnetic induction. A systematic approach to power pad design is presented in detail and the Society of Automotive Engineers (SAE) recommended practice J2954 is followed for designing the physical dimension of these power pads. To this end, Finite Element Analysis (FEA) tool ANSYS Maxwell 3D is used for simulation. Extensive simulation studies are carried out to verify the efficiency of the proposed DDC power pad. It is found that the proposed DDC power pad offers significantly improved performance compared to the existing circular and DD power pads under various misaligned positions.
