【摘要】：双频段无线电能传输系统可以提供两个不同频率的传输通道以实现电能和信号的同步传输。根据单一谐振频率的电能传输线圈的阻抗特性提出了双频段无线电能传输线圈的设计思路,并设计了双频段磁耦合谐振式无线电能传输系统,系统接收端采用陷波电路分离信号和电能。构建部分元等效电路对线圈阻抗特性、系统电能传输能力和传输效率进行计算,由此得出系统可同步传输信号并且不影响其电能传输效率。最后,设计了和理论计算系统参数一致的实验装置进行实验验证,结果与理论分析具有较好的一致性,验证了设计方法的有效性。
[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.
