摘要
利用弱电感耦合原理研制一种小功率高效无线能量传输系统。发射系统由多股线绕制的电感线圈与自制高Q值大容量可变电容构成,驱动电路为开关电路.输出功率1.0W,可点亮4m外红色发光二极管。发射端与接收端的距离S与发射端线圈直径D之比达S/D=16倍。接收线圈直径可小于发射线圈直径。
A high efficient small power wireless transfer system has been designed based on strong coupling.The emission source is composed of a self-made multi-conductor inductor and a high Q capacitor,driven by switching circuit.While the output power is 1.0 W,a red diode in 4m far away can be lightened.The ratio of the distance between the source and the receiver(S) and the diameter of the source coil(D) can reach S/D = 16.The diameter of receive coil can be much smaller than source coil.
