摘要随着电子信息产业的发展，人们对手机的依赖性也越来越大。除此之外，手机屏幕越来越大，功能越来越全。更加频繁的使用手机带来的手机功耗也越来越大。因此，人们给手机充电的次数也会有所增加。随之而来的就是，感到拉扯充电线的繁琐和手机充电接口的损坏率的提高。不仅如此，手机的更新换代会是大家更加购买新的产品而原先手机上的充电器将会浪费。大量的废旧充电器势必会带来处理困难、环境污染和资源浪费等问题。74056

   由此可见，手机无线充电技术会解决以上问题。本文通过对手机无线充电装置的研究，阐述了手机电磁感应式充电的工作原理，设计装置电路，探究影响无线充电的因素。并采用了无线电波和电磁共振的方法来实现手机无线充电。此外，还详细的阐述了第一个无线充电标准¬¬¬—Qi标准。

本设计完成了总体设计方案，确定电磁感应参数，绘制电路，制作PCB，测试等一系列工作。为手机无线充电系统的研究提供了一定的借鉴和参考，并对手机无线充电技术的使用起到了一定的推动作用。

Design of wireless charging device for mobile phone

Abstract With the development of electronic information industry, people on the phone dependence is also growing。 In addition, the phone screen bigger and bigger, more functional whole。 More frequent use of mobile phones has brought mobile phone power consumption is also growing。 Thus, the number of people to charge their cell phones will increase。 Attendant is felt cumbersome and pull charging cable phone charging interface to increase the rate of damage。 Moreover, the handset replacement will be more people to buy a new product while the original phone charger will be wasted。 A large number of waste treatment charger is bound to bring difficulties, environmental pollution and waste of resources and other issues。

   Thus, the mobile wireless charging technology will solve the above problems。 Through the research on wireless phone charging device, elaborated phone electromagnetic induction charging working principle, circuit design device, wireless charging explore the impact of factors。 And uses radio waves and electromagnetic resonance methods to achieve mobile wireless charging。 In addition, the detail of the first wireless charging standard,Qi standard。

The design is completed the overall design to determine the parameters of electromagnetic induction, draw the circuit, making PCB, test and a series of work。 Mobile wireless charging system for the study provides some useful references, and the use of mobile wireless charging technology has played a certain role。

This paper has 15 figures, 26 tables, 160 references。
