【摘要】：近年來(lái)，越來(lái)越多的電子產(chǎn)品的涌現(xiàn)使得如何充電日益受到關(guān)注，太多的充電設(shè)備已經(jīng)成為負(fù)擔(dān)，無(wú)線能量傳輸技術(shù)成為研究熱點(diǎn)。其中的磁耦合諧振式無(wú)線能量傳輸技術(shù)具有優(yōu)異的傳輸效率和能較遠(yuǎn)的傳輸，是目前國(guó)際上主流的研究無(wú)線充電設(shè)施的技術(shù)。關(guān)于磁耦合諧振式無(wú)線電能傳輸，其傳輸距離對(duì)無(wú)線電能傳輸來(lái)說(shuō)是一個(gè)很大的挑戰(zhàn)，因此，本文對(duì)磁耦合諧振式無(wú)線能量傳輸技術(shù)的發(fā)射和接收線圈的結(jié)構(gòu)參數(shù)進(jìn)行了基礎(chǔ)性理論研究。 根據(jù)磁耦合諧振式無(wú)線電能傳輸技術(shù)的理論分析研究，本文采用Hilbert分形線圈代替環(huán)形的發(fā)射線圈和接收線圈。分析了系統(tǒng)的傳輸機(jī)理，能量傳輸以及應(yīng)該遵守的準(zhǔn)則，以往研究中都是耦合模公式建立數(shù)字模型，具有一定的缺點(diǎn)。針對(duì)這一問(wèn)題，首先，利用互感耦合建立的數(shù)字模型，然后用電路理論分析建立等效的電路模型，能夠?qū)Ⅰ詈夏９浇?shù)字模型簡(jiǎn)化，很好的分析影響能量傳輸?shù)年P(guān)鍵因素。 在無(wú)線電能傳輸系統(tǒng)中，本文利用Hilbert分形天線代替?zhèn)鹘y(tǒng)的環(huán)形線圈，在很大程度上減小了接收端尺寸。在此基礎(chǔ)上，分析影響能量傳輸?shù)年P(guān)鍵因素，得到系統(tǒng)傳輸?shù)淖畲髠鬏斝省?利用上述方法對(duì)磁耦合無(wú)線電能傳輸進(jìn)行仿真實(shí)驗(yàn)，，通過(guò)計(jì)算傳輸距離，傳輸效率等幾個(gè)參數(shù)對(duì)系統(tǒng)性能進(jìn)行評(píng)估。結(jié)果及其分析表明在相同的發(fā)射和接收面積下，Hilbert分形天線代替環(huán)形天線，能夠較好的傳輸能量，有效地減小了接收端尺寸。對(duì)比于其他的磁耦合諧振式無(wú)線電能傳輸，該方法對(duì)接收端尺寸明顯減小，保證了傳輸距離和傳輸效率同時(shí)也滿足了無(wú)線電能傳輸?shù)囊蟆?br/>[Abstract]:In recent years, the emergence of more and more electronic products, how to charge more and more attention, too many charging equipment has become a burden, wireless energy transmission technology has become a research hotspot. The magnetically coupled resonant wireless energy transmission technology, which has excellent transmission efficiency and far away transmission, is the mainstream technology in the world to study wireless charging facilities. With regard to the transmission of magnetically coupled resonant radio energy, the transmission distance is a great challenge for radio energy transmission. In this paper, the structure parameters of transmitting and receiving coils of magnetic coupling resonant wireless energy transmission technology are studied theoretically. According to the theoretical analysis and study of the magnetically coupled resonant radio energy transmission technology, the Hilbert fractal coil is used to replace the ring transmitting coil and the receiving coil. The transmission mechanism of the system, the energy transmission and the criteria that should be observed are analyzed. In the past, the coupled mode formula is used to establish the digital model, which has some shortcomings. In order to solve this problem, the digital model established by mutual inductance coupling and the equivalent circuit model by circuit theory analysis can be used to simplify the digital model of coupling mode formula and analyze the key factors that affect energy transmission. In the radio energy transmission system, the Hilbert fractal antenna is used to replace the traditional ring coil, which greatly reduces the size of the receiver. On this basis, the key factors affecting energy transmission are analyzed, and the maximum transmission efficiency of the system is obtained. The system performance is evaluated by calculating the transmission distance and transmission efficiency. The results show that the Hilbert fractal antenna can replace the annular antenna under the same transmitting and receiving area, which can transmit better energy and reduce the size of the receiver effectively. Compared with the other magnetically coupled resonant radio energy transmission, the size of the receiver is reduced obviously, and the transmission distance and transmission efficiency are guaranteed to meet the requirements of radio energy transmission at the same time.
