摘要
无线充电技术是一种采用无线方式进行电能传输的技术。首先研究了无线充电器的基本工作原理,然后针对无线充电器充电过程中充电效率低下的问题,利用ANSYS有限元软件进行耦合仿真,分析比较了单线圈与三线圈无线充电器在不同侧移距离时的充电效率,分析结果表明单线圈充电效率更高,三线圈充电器充电效率更稳定,为多线圈充电器的设计提供了理论依据。
Wireless charging technology is a kind of power transmission technology through using wireless mode. First of all, the basic working principle of the wireless charger is researched, and then, in view of the low charging efficiency of wireless charger, and the charging efficiency of single coil and three coils wireless chargers at different sidetrack distances is analyzed and compared through the coupling simulation of ANSYS finite element software. The analysis resuits show that single coil charging efficiency is higher, and the charging efficiency of three coils charger is more stable, which provides a theoretical basis for the design of multi-coil charger.
