Factors Influencing the Optimization of Magnetically Coupled Coil Structures-Analysis and Discussions

The paper explores the factors influencing the optimization of magnetically coupled coil structures through in-depth analysis and discussions. Optimizing the wireless power transfer system (WPTS) is crucial as it enhances the efficiency, reliability, and overall performance of the system, leading to more effective and sustainable wireless energy transmission solutions. The optimization process involves considering multiple aspects, such as coil structure, configuration, number of turns, coil shape, working frequencies, electromagnetic properties of the medium, and coil distance. To identify the relevant parameters (R, L, C, and G) for a system consisting of two magnetically coupled coils used WPTS, advanced electromagnetic field numerical simulation software is employed. Among the widely utilized software tools for estimating the parameters of electromagnetic systems is the ANSYS Q3D EXTRACTOR, available in both 2D and 3D versions.
