【摘要】：随着科技的飞跃发展，手机，数码相机，平板电脑等手持设备已经成为了人们日常生活必不可少的一部分，而且更新换代的速度也尤其迅速。如此迅速的更换频率必将带来一个严重的问题，就是废旧电子产品对环境的污染。用户每更换一部手机，意味着旧的手机充电器基本被废弃。由于有线充电器有不易携带、接头损坏会有触电的危险的缺点，所以，对无线充电、能量传输效率高的研究成为一种趋势。无线充电技术产生在电子产品更新换代时，减少了废弃充电器的产生，通用性和兼容性可以有效减少废弃充电器对环境污染，并将会使人们的生活更加方便。本课题基于电子感应原理研究设计了一款针对移动设备的无线充电系统。该系统发射端控制芯片采用BQ500211、INA199A、RT9818A及MSP430G2001等芯片进行硬件电路设计，，包含全桥逆变线路，LED控制线路和其他保护线路；接收端设计模块采用SN51013B芯片进行电路设计。系统的设计中，充分考虑了发射线圈，接收线圈以及接触距离对系统性能的影响，通过不断调整线圈的设计，电压动态调整以及谐振频率的调整，系统性能得到大幅度提升。系统的最大发射功率达到5W，有效充电距离达到1cm左右。本课题第一章为引言，介绍无线充电技术的背景，原理和目前的现状；第二章为无线充电系统的设计与实现，从发射端设计，接收端设计以及线圈设计分别详述了整个设计过程；第三章为无线充电系统功能验证，分别测试发射端和接收端的参数是否满足Qi标准设计，并对测试结果进行分析；第四章为总结与展望，主要针对本课题的设计心得，提出自己对整个无线充电系统的发展的一些看法。
[Abstract]:With the rapid development of technology, mobile phones, digital cameras, tablets and other handheld devices have become an essential part of people's daily life, and the pace of upgrading is particularly rapid.Such a rapid change of frequency will bring a serious problem, that is, waste electronic products pollution to the environment.Every time a user changes a mobile phone, the old phone charger is basically abandoned.Because the wired charger is not easy to carry and the damage of the connector can cause the danger of electric shock, the research on wireless charging and high energy transmission efficiency has become a trend.Wireless charging technology is produced when electronic products are updated, reducing the generation of waste chargers. The generality and compatibility can effectively reduce the environmental pollution of waste chargers, and will make people's lives more convenient.Based on the principle of electronic induction, a wireless charging system for mobile devices is designed.The transmitter control chip of the system uses BQ500211A199A199ART9818A and MSP430G2001 chips to design the hardware circuit, including the full-bridge inverter line, LED control circuit and other protection circuits, and the receiver design module uses SN51013B chip to design the circuit.In the design of the system, the influence of the transmitting coil, the receiving coil and the contact distance on the system performance is fully considered. By adjusting the design of the coil continuously, the voltage dynamic adjustment and the resonant frequency adjustment, the system performance is greatly improved.The maximum transmission power of the system is 5 W and the effective charging distance is about 1cm.The first chapter introduces the background, principle and current situation of wireless charging technology, the second chapter is the design and implementation of wireless charging system, from the transmitter design,The design of the receiver and the coil are described in detail. The third chapter is the function verification of the wireless charging system. The parameters of the transmitter and receiver are tested to meet the Qi standard design, and the test results are analyzed.The fourth chapter is a summary and prospect, mainly aiming at the design experience of this subject, put forward some views on the development of the whole wireless charging system.
