该设计的原理就是通过电磁波传递电能。用555单片机时基集成电路产生一个12kHz峰峰值为5V的方波，通过反相器整形，放大，最终放大成峰峰值为12V的方波。最后，用三个反相器并联，驱动H桥，在H桥的输出端输出一个峰峰值为21.2v的方波。然后，用H桥驱动发射线圈，将电能转换成电磁波发射出去。接收线圈集成在手机里面，将手机放到底座上，两个线圈通过磁耦合就能传递能量。接收线圈输出的交流信号通过整流桥整流，电容滤波，最后变成稳定的直流电压，这样就可以对手机进行无线充电了。

The principle of this work is the power passed through the electromagnetic waves.First, 555 integrated circuit to generate a 12kHz square wave of peak-to-peak value of 5V.Shaping through an inverter, such as ampliifcation processing, and ultimately zoom into a peak value of 12V square wave.Three parallel inverter drive H-bridge and output a square wave peak-to-peak value of 21.2v.Drive the transmitter coil, the electrical energy is converted into an electromagnetic wave and transmitted. The receiving coil integrated on the phone, put the phone on the base then the two coils transfer energy via magnetic coupling. The AC signal of the receiver coil output is through the rectiifer, the a stable ifltering, the ifnal output of the DC voltage to the mobile phone for charging.
