【正文】 摘 要 I 摘 要 隨著科學(xué)技術(shù)的發(fā)展，各種不同功能的便攜式電子產(chǎn)品充斥著當(dāng)今社會(huì)，如手機(jī)、 PDA、數(shù)碼播放器和相機(jī)、筆記本電腦等。在實(shí)際運(yùn)用這些設(shè)備中，每個(gè)產(chǎn)品都對(duì)應(yīng)一個(gè)與之匹配的充電器。這種方式 既 浪費(fèi)資源、增加產(chǎn)品的成本， 且 不利于環(huán)保 的要求。其問(wèn)題的關(guān)鍵所在就是充電器不具備通用性，更為重要的是，絕大部分電子產(chǎn)品都是傳統(tǒng)的有線(xiàn)充電模式，對(duì)使用者來(lái)說(shuō)充電比較麻煩。而具有統(tǒng) 一標(biāo)準(zhǔn)的無(wú)線(xiàn)充電器具有如下優(yōu)勢(shì)：方便、多機(jī)共用、換機(jī)不換充電器，這些優(yōu)勢(shì)可以有效地解決上述問(wèn)題。 基于此，本論文在無(wú)線(xiàn)充電方面做了一些研究。其 內(nèi)容主要集中在以下幾個(gè) 方面：概述了無(wú)線(xiàn)充電技術(shù)原理及無(wú)線(xiàn)充電技術(shù)的發(fā)展情況，針對(duì)影響無(wú)線(xiàn)充電系 統(tǒng)指標(biāo)的關(guān)鍵技術(shù)進(jìn)行分析，特別突出了能量發(fā)射模塊和電源管理模塊 的設(shè)計(jì)特點(diǎn) ,通過(guò)不斷的測(cè)試和論證， 為提高 整套系統(tǒng)的傳輸 效率 和充電效率提出了幾種解決方案。通過(guò)針對(duì)該設(shè)計(jì)存在的不 足，對(duì)未來(lái)的無(wú)線(xiàn)充電技術(shù)進(jìn)行展望。最后就本論文涉及的核心內(nèi)容進(jìn)行總結(jié)，旨在說(shuō)明本課題研究的成果、價(jià)值 以及 意義。 關(guān)鍵字 ： 無(wú)線(xiàn)傳能 ， 無(wú)線(xiàn)充電 ， 電磁感應(yīng) ABSTRACT ABSTRACT II ABSTRACT With the development of science and technology, a variety of portable electronic products bee 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 shortings of the design, the future prospect of wireless charging technologies has been discussed. Finally, this thesis summarizes involving the core content of this subject, aiming to say the research achievement, value and significance.
