【摘要】：無線電能傳輸技術(shù)是一種以電場和磁場為介質(zhì)的新型電能傳輸技術(shù)。目前無線電能的三種主要傳輸方式為感應(yīng)耦合式、電磁波輻射式、磁耦合諧振式，相對于前兩種傳輸方式，磁耦合諧振式在傳輸特性、傳輸方向性、穿透性和安全性等方面都具有較大的優(yōu)勢，因此該傳輸方式引起了國內(nèi)外研究人員的重視，成為當(dāng)前共同關(guān)注的熱點(diǎn)并具有良好的發(fā)展前景。 本文首先簡要分析了磁耦合諧振式無線電能傳輸系統(tǒng)的基本工作原理，及實(shí)現(xiàn)無線電能傳輸?shù)拇篷詈虾椭C振兩大關(guān)鍵因素。在此基礎(chǔ)上，，設(shè)計完成了串聯(lián)-串聯(lián)拓?fù)溲a(bǔ)償式磁耦合諧振無線電能傳輸系統(tǒng)，并搭建實(shí)驗(yàn)平臺進(jìn)行了實(shí)驗(yàn)驗(yàn)證。 基于電路理論對所設(shè)計系統(tǒng)的等效諧振耦合回路進(jìn)行了建模分析，得出影響系統(tǒng)傳輸特性的因素，包括傳輸距離、諧振頻率、品質(zhì)因數(shù)等。然后分別以傳輸距離、諧振頻率、品質(zhì)因數(shù)為變量，分析研究輸出功率和傳輸效率特性，并進(jìn)行了Matlab仿真和實(shí)驗(yàn)驗(yàn)證。為解決系統(tǒng)在滿足輸出功率較大時，傳輸效率卻比較低的問題，本文提出了功效積這一綜合系統(tǒng)評估指標(biāo)，從而實(shí)現(xiàn)系統(tǒng)參數(shù)的優(yōu)化，并就系統(tǒng)在最大功率和最大功效積兩個指標(biāo)下的輸出功率和傳輸效率進(jìn)行了對比分析，最后通過Matlab仿真和實(shí)驗(yàn)結(jié)果驗(yàn)證了功效積指標(biāo)的可行性。
[Abstract]:Radio energy transmission technology is a new type of electric energy transmission technology with electric field and magnetic field as the medium. At present, the three main transmission modes of radio energy are induction coupling, electromagnetic wave radiation, magnetic coupling resonance, compared with the first two transmission modes. Magnetic coupling resonance has great advantages in transmission characteristics, transmission direction, penetration and security, so the transmission mode has attracted the attention of researchers at home and abroad. It has become the focus of common concern and has a good development prospect. In this paper, the basic working principle of the magnetically coupled resonant radio energy transmission system and the two key factors of magnetic coupling and resonance in the realization of wireless power transmission are briefly analyzed in this paper. A series-series topology compensated magnetically coupled resonant radio transmission system is designed and the experimental platform is built to verify it. Based on the circuit theory, the equivalent resonant coupling circuit of the designed system is modeled and analyzed, and the factors affecting the transmission characteristics of the system are obtained, including transmission distance, resonant frequency, quality factor, etc. The quality factor is a variable. The characteristics of output power and transmission efficiency are analyzed and studied, and the Matlab simulation and experiment are carried out to solve the problem that the transmission efficiency of the system is low when the output power is high. In this paper, the function product, a comprehensive system evaluation index, is proposed to optimize the system parameters, and the output power and transmission efficiency of the system under the two indexes of maximum power and maximum effect product are compared and analyzed. Finally, the feasibility of the effectiveness product index is verified by Matlab simulation and experimental results.
