【摘要】：雙頻段無線電能傳輸系統(tǒng)可以提供兩個不同頻率的傳輸通道以實現(xiàn)電能和信號的同步傳輸。根據(jù)單一諧振頻率的電能傳輸線圈的阻抗特性提出了雙頻段無線電能傳輸線圈的設(shè)計思路,并設(shè)計了雙頻段磁耦合諧振式無線電能傳輸系統(tǒng),系統(tǒng)接收端采用陷波電路分離信號和電能。構(gòu)建部分元等效電路對線圈阻抗特性、系統(tǒng)電能傳輸能力和傳輸效率進行計算,由此得出系統(tǒng)可同步傳輸信號并且不影響其電能傳輸效率。最后,設(shè)計了和理論計算系統(tǒng)參數(shù)一致的實驗裝置進行實驗驗證,結(jié)果與理論分析具有較好的一致性,驗證了設(shè)計方法的有效性。
[Abstract]:The dual band radio energy transmission system can provide two different frequency transmission channels to achieve synchronous transmission of electrical energy and signal. The design idea of a dual band radio energy transmission coil is proposed according to the impedance characteristics of the electric energy transmission coil of a single resonant frequency, and a dual band magnetic coupled resonant radio energy transmission system is designed. The receiver adopts a trap circuit to separate the signal and power. The equivalent circuit of a partial element is constructed to calculate the impedance characteristics of the coil, the power transmission capacity and the transmission efficiency of the system. Thus the system can transmit the signal synchronously without affecting the transmission efficiency of its electric energy. Finally, an experimental device which is consistent with the theoretical calculation system parameters is designed. The experimental results show that the results are in good agreement with the theoretical analysis, and the effectiveness of the design method is verified.
