This research delves deeply into the significance of material selection when it comes to the performance of magnetic couplers within wireless power transfer (WPT) systems tailored for electric vehicles (EVs). Optimal material choices for magnetic couplers are pivotal, directly influencing the efficiency and dependability of power transfer in these systems. The core objective of this study revolves around a comprehensive exploration of how the utilization of different materials in magnetic couplers affects their performance metrics, encompassing coupling efficiency, power transmission capacity, and the system’s overall reliability. Advanced simulation tools like Ansys and Matlab are harnessed for this exploration. The simulations incorporate a range of material properties, such as magnetic permeability, electrical conductivity, and thermal characteristics. These simulations unveil valuable insights into the repercussions of material selection on critical performance indicators. This includes metrics like coupling efficiency, power losses, heat dissipation, and fundamental magnetic parameters such as self-inductance (L), mutual inductance (M), magnetic flux density (B), and magnetic field strength (H). In addition, our analysis considers the weight implications arising from different material choices for the coupler. Our findings provide a valuable resource for informed material selection, ultimately striving to maximize power transfer efficiency, minimize energy losses, and ensure safety and the system’s overall reliability. Moreover, this analysis significantly contributes to the advancement of WPT technology, ushering in greater efficiency and promoting the widespread adoption of EVs by means of improved charging infrastructure.
