【摘要】：基于WiTricity磁耦合諧振式無線傳能技術(shù)是近期被熱門研究的一項(xiàng)高效率無線電能傳輸技術(shù)，無論在無線充電上還是人體植入設(shè)備無線供電上，都有極大的應(yīng)用潛力。與傳統(tǒng)的感應(yīng)耦合式無線能量傳輸技術(shù)和電磁輻射式無線能量傳輸技術(shù)相比，磁耦合諧振式無線傳能技術(shù)具有傳輸距離相對(duì)較大，傳輸效率較高，利用非輻射特性只在諧振體中傳遞能量等優(yōu)點(diǎn)。但是如何將該技術(shù)應(yīng)用于人體內(nèi)外環(huán)境的能量傳輸，，特別是如何高效的向低功耗生物植入電子器件（心臟起搏器、神經(jīng)刺激器等）供電值得進(jìn)一步研究。 本文通過設(shè)計(jì)一個(gè)磁耦合諧振式無線電能傳輸實(shí)驗(yàn)系統(tǒng)，重點(diǎn)研究該系統(tǒng)的能量傳輸特性，研究了無線傳能中四種耦合諧振拓?fù)涞奶卣�。論文著重研究了無線傳能系統(tǒng)中的諸多因素對(duì)電能傳輸效率的影響，并提出了提高無線能量傳輸效率的幾種方法和途徑。 本文從理論上證明了磁耦合諧振系統(tǒng)次級(jí)線圈負(fù)載，線圈半徑以及匝數(shù)等參數(shù)的改變都能影響系統(tǒng)無線傳能效率，并通過所設(shè)計(jì)的磁耦合諧振式無線傳能系統(tǒng)將上述理論分析進(jìn)行了驗(yàn)證。本文通過采用一種在源諧振器和設(shè)備端諧振器之間增加中繼線圈的方法，實(shí)現(xiàn)了提高較遠(yuǎn)距離無線能量傳輸效率。并在實(shí)驗(yàn)上證明了耦合諧振線圈在進(jìn)行能量傳輸時(shí)，耦合線圈的相對(duì)夾角在0到45°轉(zhuǎn)動(dòng)對(duì)能量傳輸效率并沒有太大影響，與兩諧振線圈中心軸共線時(shí)的能量傳輸效率基本一致。
[Abstract]:Magnetic-coupled resonant wireless energy transmission technology based on WiTricity is a highly efficient radio energy transmission technology which has been studied recently, whether in wireless charging or wireless power supply of human implanted devices. Compared with the traditional inductively coupled wireless energy transmission technology and electromagnetic radiation wireless energy transmission technology, the magnetic coupling resonant wireless energy transmission technology has a relatively large transmission distance. The transmission efficiency is high and the energy transfer is only in the resonator by using the non-radiative characteristics. But how to apply this technology to the energy transfer inside and outside the human body. In particular, how to efficiently supply power to low-power bioimplanted electronic devices (pacemakers, nerve stimulators, etc.) is worthy of further study. In this paper, an experimental system of magnetically coupled resonant radio energy transmission is designed, and the energy transmission characteristics of the system are mainly studied. The characteristics of four coupling resonant topologies in wireless energy transmission are studied, and the influence of many factors in wireless energy transmission system on the power transmission efficiency is studied in this paper. Several methods and approaches to improve the efficiency of wireless energy transmission are proposed. In this paper, it is proved theoretically that the change of the secondary coil load, coil radius and the number of turns in the magnetically coupled resonance system can affect the wireless energy transmission efficiency of the system. The theoretical analysis is verified by the design of the magnetically coupled resonant wireless energy transmission system. In this paper, a method of adding relay coils between the source resonator and the device end resonator is adopted. The efficiency of remote wireless energy transmission is improved, and it is proved experimentally that the coupling resonance coil is transmitting energy. The relative rotation of the coupling coil between 0 and 45 擄does not have much effect on the energy transfer efficiency, which is basically consistent with the energy transfer efficiency of the two resonant coils when the central axis is collinear.
