毕业设计（论文）-一种无线充电器的探索与设计（论文）.doc

摘 要 随着科学技术的发展，各种不同功能的便携式电子产品充斥着当今社会，如手机、PDA、数码播放器和相机、笔记本电脑等。在实际运用这些设备中，每个产品都对应一个与之匹配的充电器。这种方式既浪费资源、增加产品的成本，且不利于环保的要求。其问题的关键所在就是充电器不具备通用性，更为重要的是，绝大部分电子产品都是传统的有线充电模式，对使用者来说充电比较麻烦。而具有统一标准的无线充电器具有如下优势：方便、多机共用、换机不换充电器，这些优势可以有效地解决上述问题。 基于此，本论文在无线充电方面做了一些研究。其内容主要集中在以下几个 方面：概述了无线充电技术原理及无线充电技术的发展情况，针对影响无线充电系统指标的关键技术进行分析，特别突出了能量发射模块和电源管理模块的设计特点,通过不断的测试和论证，为提高整套系统的传输效率和充电效率提出了几种解决方案。通过针对该设计存在的不足，对未来的无线充电技术进行展望。最后就本论文涉及的核心内容进行总结，旨在说明本课题研究的成果、价值以及意义。 关键字：无线传能 ，无线充电，电磁感应 ABSTRACT With the development of science and technology, a variety of portable electronic products become more and more popular, such as mobile phones, PDA, digital cameras and players, PC and so on. In reality, each electronic product has a matched charger. However, it will not only increase the cost of products and waste resource, but also be harmful to the environment. What’s more, as all those chargers are not universal, it causes troubles to the users. Moreover, the majority of electronic chargers are wired, so charger is relatively inconvenient for the users. The wireless charger with a unified standard has the following advantages: convenience, shared charger to different electronic products. These advantages can solve the above problem effectively. Based on this, this thesis has done some research on the wireless charging. It mainly focused on the following areas: an overview of wireless charging technology principle and the development of wireless power technologies，also and the key technical analysis indicators to the wireless charging system, in particular, this thesis highlighted the energy transmitter module and power management module design features, through continuous testing and verification. To improve the transmission efficiency of the entire system and the charging efficiency, we proposed several solutions. For the shortcomings of the design, the future prospect of wireless charging technologies has been discussed. Finally, this thesis summarizes involving the core content of this sub
