59、介及展望一、 无线充电技术的历史 实际上无线供电的设想早在一百多年前就已经出现，在1890年，尼古拉·特斯拉，这位现代交流电系统的奠基者就开始构想无线供电方法，最后提出了一个非常宏大的方案把地球作为内导体；在地球与电离层之间建立起大约8Hz的低频共振，再利用环绕地球表面电磁波来远距离传输电力。在当时，特斯拉也利用线圈进行了一系列的实验，开创了无线电力传输的先河。在1990年，特斯拉开始了他的研究，并设法让电能像广播一样跨越大洋，后来因为投资巨大，这项技术“胎死腹中”。尽管特斯拉的研究最终没有结果，但是他当初的无线供电技术构想绝对是足够的大胆。 二、 无线充电技术的发展 虽然特斯拉线圈在当时没有得到推行，但是到了20世纪20年代中期，日本的H.Yagi和S.Uda从理论上完全证实了这种方案是一种区别于有线传输的特殊供电方式，目前无线供电技术主要有电磁耦合、光电耦合、电磁共振等三种不同的方式。三、供电方式，目前无线供电技术主要有电磁耦合、光电耦合、电磁共振等三种不同的方式。1、 电磁耦合 电磁耦合对电源工程师来说，在熟悉不过了，变压器就是利用这个原理来传递能量的。如果把变压器的两个绕组分开，就是某种意义上的无线供电。电动牙刷的充电就是一个典型的案例，但是用电磁耦合的方式有很大的缺点，没有高磁导率的磁芯作为介质，磁力线会严重发散到空气中
