摘　　要：提出了一种基于电磁耦合阵列定位的无线电能传输技术,并在此基础上完成了对该装置的开发与研制。通过微处理器完成对环形电磁耦合阵列线圈与接收线圈耦合度的检测,只对耦合度最高的线圈供电,使得用电设备无论处于何种方向,总有一个发送线圈与用电设备的接收线圈接近于全耦合。避免了电能浪费和电磁辐射,实现了用电设备可以在一定范围任意移动,保证了电能传输的高效率。A kind of radio transmission technology based on positioning of the electromagnetic coupling array is presented in this paper. The research and development of the equipment is completed on this basis. Through the coupling detection of electromagnetic coupling array coil and receiver coil by MCU, it can only power to the coil with highest coupling, so that it always has a sending coil and receiving coils of electrical equipment, no matter what direction it is in, close to full coupling. In this way, it can avoid wasting energy, reduce the electromagnetic radiation, and particularly, realize that the electrical equipment can be moved in a range of arbitrary, which could ensure the high efficiency of power transmission.
