Abstract

Wireless power transfer is a new technology to transfer electrical power without any physical contact between the source and the load. The aim of this paper is to propose the use of a simple, cheap and easy technique for mid range wireless power transfer. The various technologies available so far for wireless transmission of electricity and the need for a wireless system of energy transmission are discussed here. The main problem is how power is transferred wirelessly without any bad effect on environment and human. The core of the used technology is making use of the magnetic resonance concept for transmitting the power wirelessly. Electric power is transferred at a frequency of about 100 kHz in a medium distance range to light on a 3 watt lamp making use of resonance. An impedance compensating network is used to achieve maximum power transfer. The practical results are very close to these obtained using the mathematical model and the theoretical calculations. The advantages, disadvantages and new applications of Witricity are enumerated.

无线电力传输(无线照明)

无线电力传输是一种在电源和负载之间没有任何物理接触的情况下传输电力的新技术。本文的目的是提出一种简单、廉价和容易的中距离无线电力传输技术。本文讨论了目前可用于无线传输电力的各种技术以及对无线能量传输系统的需求。主要问题是如何在不对环境和人类造成不良影响的情况下无线传输电力。所使用技术的核心是利用磁共振概念无线传输电力。电力以大约100千赫的频率在中等距离范围内传输到利用共振的3瓦灯上的光。采用阻抗补偿网络实现最大功率传输。实际计算结果与数学模型和理论计算结果非常接近。列举了Witricity的优点、缺点和新的应用。
