| description | Resonant Inductive Power Transfer (RIPT) is pivotal in advanced Electric Vehicle (EV) charging systems, offering safety, reliability, and automation ease. The magnetic pad design within RIPT-based Wireless Charging Systems (WCS) significantly influences power transfer efficiency. Three-phase magnetic couplers outshine their single-phase counterparts in energy transfer capacity, offering benefits like rotating magnetic flux and reduced ferrite mass. This article analyzes a three-phase magnetic coupler design featuring a circular geometry, characterized by enhanced angular misalignment tolerance, ferrite-friendly structure, and ease of design. Named the ''Three Half Circular Coil'' (3HCC) pad, it comprises three half-circular coils arranged in a circular pattern. The performance of this design is rigorously analyzed using MATLAB and Ansys Finite Element for a 7.7 kW system. The proposed model is benchmarked against a tripolar coil, a three-phase rectangular coil, and a conventional single-phase circular coil. 7.7 kW experimental models are designed and analyzed to investigate cross-coupling effects as the coil moves away from the origin. This article underscores the critical role of RIPT in EV charging systems, highlights the advantages of three-phase magnetic couplers over single-phase, and showcases the effectiveness of the proposed 3HCC design. |
