资料介绍

磁耦合谐振式无线电能传输技术具有传输距离中等、传输效率高、能穿过非磁导性障碍物传输电能等优点,使其有望取代电池为物联网中的传感器节点无线供电。本文通过研究磁耦合谐振式无线电能传输机理,构建了传输系统的集总参数电路模型,对各模型参数进行了理论计算,并根据模型对不同传输距离下系统的传输效率与负载功率进行了分析,得出了不同耦合状态下系统获得最大负载功率的条件。

Wireless power transfer via coupled magnetic resonances which has the advantages of moderate transmission distance, high transmission efficiency, can transfer power through non-magnetic eond etc makes it possible to power sensors of the Internet of things wirelessly instead of using batteries. the lumped parameter circui! model of the wireless power transfer huilt by investigating the principle of the wireless power transfer, syst the em via coupled magnetic parameters of the model theoretically, and the transmission efficiency and load power of the system were analyzed based on uctive material In this paper, resonances was were calculated the model. The key to obtain maximum load power of the transmission system was found under different working condition.
