【摘要】：無接觸電能傳輸技術(shù)較好地克服了傳統(tǒng)導(dǎo)線傳輸技術(shù)的弊端,提高了電能傳輸?shù)陌踩院捅憷?尤其適合于一些極端特殊的用電環(huán)境,因而具有廣闊的工程應(yīng)用前景。當(dāng)前,無接觸傳能技術(shù)可劃分為三種類型,分別是電磁感應(yīng)式無接觸傳能技術(shù)、微波輻射式無接觸傳能技術(shù)以及諧振磁耦合式無接觸傳能技術(shù)(witricity)。其中由美國(guó)麻省理工學(xué)院教授于2006年提出的諧振耦合式無接觸傳能技術(shù)代表了當(dāng)前無接觸電能傳輸?shù)淖钚掳l(fā)展方向,具有另外兩種技術(shù)所不具備的諸多優(yōu)點(diǎn),是未來無接觸傳能技術(shù)發(fā)展的重要方向。因此,諧振耦合式無接觸傳能技術(shù)是目前國(guó)內(nèi)外研究的熱點(diǎn)課題之一,相關(guān)研究已經(jīng)取得了很大進(jìn)展。但在一些關(guān)鍵問題上依然存在不足和空白,尤其在實(shí)際應(yīng)用方面尚需進(jìn)一步的探索。 本文根據(jù)諧振耦合式無接觸電能傳輸?shù)脑?在綜合現(xiàn)有研究成果的基礎(chǔ)之上,對(duì)無接觸電能傳輸技術(shù)進(jìn)行了較為深入地研究和開發(fā)。提出了無接觸電能傳輸線圈的等效電路模型,并根據(jù)等效電路模型,提出了分布參數(shù)計(jì)算方法。利用matlab計(jì)算軟件對(duì)等效電路進(jìn)行特性進(jìn)行了分析和計(jì)算,獲得了線圈的阻抗特性曲線,從而確定了諧振線圈的諧振頻率,為無接觸電能傳輸線圈設(shè)計(jì)提供了計(jì)算方法和理論基礎(chǔ)。 在上述工作的基礎(chǔ)上,本文進(jìn)一步在無接觸傳能技術(shù)工程化方面進(jìn)行了探索和研究。首先,考慮到在實(shí)際應(yīng)用時(shí)線圈位置的變動(dòng)性和不確定性,設(shè)計(jì)了線圈智能控制系統(tǒng),使無接觸傳能線圈能實(shí)時(shí)調(diào)整線圈的物理狀態(tài),以保證系統(tǒng)隨時(shí)保持在最佳工作狀態(tài)。然后,設(shè)計(jì)了微型無線充電系統(tǒng),為無接觸電能傳輸技術(shù)的開發(fā)工作奠定了基礎(chǔ)。
[Abstract]:Contactless power transmission technology has overcome the disadvantages of traditional traverse transmission technology, improved the security and convenience of power transmission, especially suitable for some extremely special electricity environment, so it has a broad engineering application prospect. At present, contactless energy transfer technology can be divided into three types, namely electromagnetic induction non-contact energy transfer technology, microwave radiation non-contact energy transfer technology and resonant magnetic coupling non-contact energy transfer technology (witricity). The resonant coupled contactless energy transfer technology, which was proposed by MIT professor in 2006, represents the latest development direction of contactless power transmission, and has many advantages that the other two technologies do not have. It is an important direction for the development of contactless energy transfer technology in the future. Therefore, resonant coupled contactless energy transfer technology is one of the hot topics at home and abroad, and great progress has been made. However, there are still shortcomings and gaps in some key issues, especially in practical applications. Based on the principle of resonant coupled contactless power transmission and on the basis of existing research results, the contactless power transmission technology is deeply studied and developed in this paper. The equivalent circuit model of contactless electric power transmission coil is presented. According to the equivalent circuit model, the calculation method of distribution parameters is proposed. The characteristic of equivalent circuit is analyzed and calculated by using matlab software. The impedance characteristic curve of the coil is obtained, and the resonant frequency of the resonant coil is determined. The calculation method and theoretical basis are provided for the design of contactless electric power transmission coil. On the basis of the above work, the engineering of contactless energy transfer technology is further explored and studied in this paper. Firstly, considering the variation and uncertainty of coil position in practical application, a coil intelligent control system is designed to make the contactless energy transfer coil adjust the physical state of the coil in real time, so that the system can be kept in the best working state at any time. Then, the micro wireless charging system is designed, which lays a foundation for the development of contactless power transmission technology.
