Spring '07 Senior Design Project
A side project to the wireless ipod charger. The efficiency is pretty low but we needed to test our project first on an LED. We are planning on increasing the radius and see what the outcome will be. Range can be about 2 ft.

This is a small scale demonstration of wireless power transfer between two coupled parallel LC tuned circuits, each consisting of a copper conductor loop acting as an inductor and a capacitor. Both LC circuits are tuned to equal individual resonant frequencies. One of them is a part of a 1.5Mhz radio frequency oscillator powered by 12 volts DC, while another is loaded by a 24V 5W incandescent light bulb. Brought in proximity, copper loops share a small mutual inductance, essentially forming a transformer. In order to transmit significant amount of power through this transformer a very large amount of reactive power needs to circulate in it's primary, requiring use of a thick copper tube for the conductor, and a bank of eight 6.8nF capacitors in parallel.
Receiver coil's leakage inductance is in turn canceled out by another capacitor, allowing for the maximum power transfer to the load.
这是一个小规模示范的两个耦合并联LC调谐电路,每个的铜导体环路作为一个电感器和一个电容器组成之间的无线电力传输。两个LC电路调谐平等个别的共振频率。其中之一是12伏直流供电的一个1.5MHz射频振荡器的一部分,而另一个是由一个24V 5W白炽灯加载。在靠近诉,铜线环路分享一个小的互感,基本上形成了一个变压器。为了通过这个变压器传输功率相当数量的无功功率量非常大,需要在它的主要流通,需要使用厚铜管导体,八个6.8nF电容并联的银行。
接收线圈的漏感,又取消另一个电容,允许的最高权力移交给负载。
Experimenting with copper loop orientations, one can find positions of the receiver close to transmitter where no power is received, as total magnetic flux crossing through the receiver loop is zero. Hence this is a directional method of power transmission.
铜循环的方向与试验,人们可以找到接收的位置靠近变送器没有收到电源,通过接收机环路穿越的总磁通量为零。因此这是一个电力传输的定向方法。
Due to small size of the apparatus very little power is actually radiated in far field, with losses being mainly ohmic heating. Hence this method is also sometimes known as non-radiative or near-field power transmission.
由于该仪器体积小,非常小的功率实际上是在远场辐射,主要是欧姆加热的损失。因此,这种方法有时也被称为非辐射或近场功率传输。

Concept is similar to MIT's recent work. Power electronic oscillator drives an Air-cored resonant transformer at approximately 1MHz.
麻省理工学院最近的工作概念是类似的。电力电子振荡器驱动器空芯约1MHz的谐振变压器。
The load is a 12Vdc 1A brushless CPU fan and an orange LED.
负载是12V直流1A无刷CPU风扇和一个橙色的LED。
I have written a step-by-step design guide which both motivates a lot of the design choices and also explains in detail how the circuit works. This guide can be found online at:

A simple demonstration of wireless energy transfer. Using a similar setup as nikola tesla used at the turn of the 20th century. Several LEDs are lit up wirelessly from a telsa magnifying transmitter, which is just a more efficient tesla coil design.

A wireless power transmitter, running at 63KHz, that lights a 12V bulb from a 10cm distance. It can be seen that is important to have the receiver correctly aligned for maximum performance. Schematics and more details here: http://www.pocketmagic.net/?p=2143

剧情:费城实验的进行具有着深远的意义,它不仅证实了自然界中的确有我们看不到的另外空间的存在,同时也表明将人类及装备暂时投入另一空间的可行。
