【摘要】：無線電力傳輸技術(shù)作為二十一世紀(jì)最受國際社會關(guān)注的技術(shù)之一，已經(jīng)開始進入人們的生活。磁共振耦合無線電力傳輸技術(shù)因其在中距離上實現(xiàn)電能高效傳輸?shù)奶攸c，吸引了大量相關(guān)研究人員進行研究與探索。 本文根據(jù)耦合模理論對磁共振耦合無線電力傳輸技術(shù)的工作原理及相關(guān)特性做了詳細(xì)的理論分析，推導(dǎo)出了磁共振耦合無線電力傳輸系統(tǒng)的傳輸效率、耦合系數(shù)、品質(zhì)因數(shù)等參數(shù)的計算公式，給出了發(fā)射線圈和接收線圈的設(shè)計依據(jù)，設(shè)計并制作了幾組線圈，通過實際測試驗證了所給依據(jù)的合理性。 論文著重對磁共振耦合無線電力傳輸系統(tǒng)的傳輸特性進行了實驗驗證。所設(shè)計的線圈具有良好的方向性；系統(tǒng)在發(fā)射線圈和接收線圈同時發(fā)生諧振時，能獲得很高的傳輸效率；存在頻率分裂現(xiàn)象，即系統(tǒng)有兩個關(guān)于中心頻率對稱的諧振頻率，在這兩個頻率上都能獲得最大的傳輸效率；隨傳輸距離的增加，兩諧振頻率逐漸向中心頻率靠攏，，且在高諧振頻率點處的傳輸效率先增大后減小，而在低諧振頻率點處，傳輸效率逐漸降低。 文中提出了磁共振耦合無線電力傳輸系統(tǒng)的接收電路設(shè)計方案。采用二極管橋式整流電路實現(xiàn)射頻到直流的轉(zhuǎn)換，完成高頻整。根據(jù)歸一化低通濾波器參數(shù)設(shè)計出適合系統(tǒng)需求的低通濾波器。完成了實際電路的測試與系統(tǒng)調(diào)試，并點亮了1米外的3瓦燈泡。
[Abstract]:Wireless power transmission technology, as one of the most concerned technologies in the 21 century, has begun to enter people's lives. Magnetic resonance coupled wireless power transmission technology has attracted a large number of researchers to study and explore because of its high efficiency power transmission in middle distance. Based on the coupled mode theory, this paper makes a detailed theoretical analysis of the working principle and related characteristics of the magnetic resonance coupled wireless power transmission technology, and deduces the transmission efficiency and coupling coefficient of the magnetic resonance coupled wireless power transmission system. The design basis of transmitting coil and receiving coil is given. Several sets of coils are designed and made. The rationality of the basis is verified by practical test. The transmission characteristics of magnetic resonance coupled wireless power transmission system are verified experimentally in this paper. The designed coil has good directionality, the system can obtain high transmission efficiency when the transmitting coil and the receiving coil are resonant at the same time, and the frequency splitting phenomenon exists, that is, the system has two resonant frequencies about the center frequency symmetry. The maximum transmission efficiency can be obtained at both of these two frequencies. With the increase of transmission distance, the two resonant frequencies are gradually closer to the center frequency, and the transmission efficiency at the high resonant frequency point increases first and then decreases, while at the low resonant frequency point, the transmission efficiency increases firstly and then decreases at the low resonant frequency point. The transmission efficiency is decreasing gradually. In this paper, the receiving circuit design of magnetic resonance coupled wireless power transmission system is presented. Using diode bridge rectifier circuit to achieve RF to DC conversion, complete high-frequency integration. According to the normalized low pass filter parameters, a low pass filter suitable for the system requirement is designed. Completed the actual circuit testing and system debugging, and lit a 3-watt light bulb 1 meter away.
