Abstract

Wireless power transfer (WPT) technologies have revolutionized the way electric vehicles (EVs) are charged by removing the requirement for physical connections, thus enhancing both convenience and safety. In serial–serial (SS) WPT systems, the mutual link of inductive coupling involves several critical factors that must be considered to achieve efficient power transfer, including coil design, Q factor, coil alignment, and resonance. This paper presents a new approach to designing and optimizing magnetic cores and shields to enhance the performance of square coils integrated with ferrite boxes, ultimately contributing to the broader field of WPT technology while reducing susceptibility to variations in the air gap. Furthermore, the geometric parameters and materials of the coils should be appropriately designed or selected to achieve excellent performance. We have analyzed the potential impacts of the shield on power transfer efficiency. With the proposed modified shields, the coupling between poorly coupled coils is improved, and the quality factor is increased, enabling loosely coupled WPT systems to function effectively. The results validate the efficacy of the solution proposed, demonstrating its capacity to transfer 3.7 kW with an effective rate around 89.7 % The effects of the modified magnetic shields on power transfer were investigated through a theoretical study using the finite element method (FEM) in Ansys Maxwell software.
