摘要
当人们的上网方式逐渐从有线过渡到无线时,更多的用户期待着电能的传输也能像无线网络一样摆脱线的束缚。文章提出了一种基于磁耦合共振的无线输电系统设计方案。该系统的基本构成是两个铜线圈,天花板上的发射线圈与交流电源相连,桌面下的接收线圈与移动设备相接。利用两个相同频率的谐振线圈产生的强耦合,使电能以无线方式从电源插座传输给置于桌面的笔记本电脑和手机。
When the way to access Internet gradually changes from wired to wireless,more users look forward that the power transmission can be as free as the wireless network without wires.This paper presents the design of wireless power transmission system based on magnetic resonant coupling.The basic design for the system is to use a couple of copper coils,with the transmitter in the ceiling connected to AC power supply,and the receiver under the table that is attached to mobile devices.The resonant nature of the process ensures a strong coupling between the two resonant coils,so that the electrical energy will transmit from the power outlet to laptops and cell phones on the table wirelessly.
