摘要
针对磁耦合共振型无线充电系统中耦合线圈,对传统的两线圈耦合进行分析并设计出三线圈的耦合模型。利用Maxwell有限元仿真软件对两线圈耦合模型以及三线圈耦合模型进行有限元仿真。利用Multisim仿真软件设计出整体无线充电电路对电路进行仿真。验证三线圈与两线圈耦合模型的传输效率,并得出在距离相等的条件下三线圈每个接收线圈与两线圈的接收线圈的传输效率接近,但由于三线圈有两个接收线圈可以同时工作,更具实际意义。
In this paper, the coupling of the coil in the magnetically coupled resonant wireless charging system is analyzed, and the coupling of the two coils is analyzed and the coupling model of the three coils is designed. The two coil coupling model and the coupling model of the three coils are simulated by Maxwell finite element simulation software. Using Muhisim simulation software to design the whole wireless charging circuit to simulate the circuit. The transmission efficiency test three and two coils coupled model, finally draw close to the transmission efficiency of the receiving coil distance under the condition of the same three coils of each receiver coil and the two coil, but due to the three coil with two receiving coil can work at the same time, more practical.
