Design of wireless energy transmission system based on LCC-S

Abstract Due to the low coupling coefficient of orbital wireless energy transmission, to improve the efficiency of the system, this paper analyzes the ferrite structure of the receiving coil with the help of Maxwell simulation software. Firstly, the models of the traditional E-type ferrite-wound receiving coil and the C-type ferrite-wound receiving coil are respectively constructed and analyzed in comparison, and it is found that the latter efficiency is at least 5% higher than that of the former. After selecting the C-type ferrite structure, a 3D finite element parametric model of the system is constructed in Maxwell, and the optimal opening size is analyzed.
