Wireless power transfer at MHz frequencies

无线或感应充电在汽车、船舶和航空航天领域越来越受到关注，与插入式充电相比，它具有显著的优势。目前的项目将着眼于在MHz区域运行的系统，该系统提供更高的功率密度，因此尺寸更小，并且可以容忍发送和接收线圈之间的更大距离。该项目将重点评估两种新的线圈技术，即谐振环谐振器和带有导电涂层的陶瓷环。这些选项最初将使用COMSOL多物理场包进行建模。然后将构建测试单元并对其性能进行评估，并与使用印刷电路板和铜或铝管的基准解决方案进行比较。最后，有可能在WMG的一辆电动汽车上安装一个系统。该项目将与WMG的无线充电研究团队密切合作。

Wireless or inductive charging is of increasing interest for the automotive, marine and aerospace sectors, bringing for significant benefits over plug in charging arrangements. The present project will look at systems operating in the MHz region which offer higher power densities, hence smaller size, and can tolerate greater distances between send and receive coils. The project will focus on evaluating two new coil technologies namely the resonant ring resonator and ceramic rings with conductive coatings. These options will be initially be modelled using the COMSOL multiphysics package. Test units will then be constructed and evaluated and performance compared to benchmark solutions using printed circuit boards and copper or aluminium tubes. Finally there is the possibility of installing a system on one of WMG's electric cars. The project will be carried out in close collaboration with the wireless charging research team at WMG.
