摘要

这项工作描述了在低频下呈现强耦合磁共振(SCMR)的三线圈系统的特性。研究了线圈间功率传输效率的理论模型，以预测不同位置的辅助线圈在传输中间的系统行为。为这种低频系统找到了确定影响性能的每个参数(电感、耦合系数和质量因子)的最佳方法。在一个典型的双线圈系统中，通过在中间增加一个优化的辅助线圈，功率传输效率提高了270倍。理论模型与实验结果吻合良好。

Modelling approach for low-frequency strongly coupled magnetic resonance wireless power transfer system

This work describes the characterization of a three coil system presenting strongly coupled magnetic resonance (SCMR) at low frequency. A theoretical model for the power transmission efficiency between coils is studied, in order to predict the system behaviour, for different positions of the auxiliary coil placed in the middle of the transmission. The best approach for determining each parameter that impacts the performance (inductance, coupling coefficients and quality factor) is found for this low-frequency system. The power transfer efficiency of a typical two coil system is increased 270 times by adding an optimized auxiliary coil in the middle. Theoretical models and experimental measures are in good agreement.
