本文参照Youtube原视频链接：
01 无线电能传输
一、背景介绍
今天在Youtube上看到一个短视频， 给对无线电能传送进行了简明生动的说明。 特别是视频中给出了一个人人都可以重复实验的电路， 可以完成对手机的无线充电。 今天将这个短片中的电路介绍给参加全国大学生智能车竞赛的同学们， 可以帮助大家快速入门， 并开始进一步设计更加高能、高效的无线电能传送电路。
二、电路设计
1、发送电路
这是发送电路的原理图，它包括有一个大功率MOS管， 作者将其在一个洞洞板上进行焊接， 接上5V电源，电路便开始震荡工作。 这个电路非常简单，也比较容易制作。
下面是发送电路的原理图，实际制作的发射器可以参见本文的视频中的内容。
▲ 图1.2.1 发射电路原理图
2、接收电路
接收电路相对比较简单，它包含有接收线圈，全桥整流，滤波电容以及稳压输出电路等。 这个电路在接收端没有使用谐振电容。 输出进行稳压之后，便可以直接对手机进行充电了。

本文讨论了一个Youtube上视频短片介绍的无线传输电路， 视频作者特别使用浅显易懂的方式对原理进行了介绍， 令人感兴趣的是他的实际制作，更能激起初学者进行复制学习。 这个短片值得大家看一下。
