Study of wireless power transmission system of small size resonator

  • 摘要: 针对目前小型无线充电设备的传输效率随发射端和接收端距离的变化而波动的问题,根据无线能量传输系统数学模型,分析了频率分裂的相关因素。在发生频率分裂时不改变谐振频率和阻抗参数的条件下,通过调整两谐振线圈的径向距离来削弱两线圈的互感系数,从而抑制频率分裂现象,提高传输效率。最后搭建了小型谐振器无线电能传输系统实验平台。实验结果表明,该系统可成功对负载进行充电,具有良好的传输性能,适用于小型无线能量传输设备。
    Abstract: In view of the problem that transmission efficiency of small wireless charging devices changes with distance between transmitter and receiver, relevant factors of frequency splitting were analyzed according to mathematic model of wireless energy transmission system. Under the condition that resonant frequency and impedance parameters do not change when frequency splitting occurs, mutual inductance of two resonance coils can be reduced by adjusting radial distance of the two coils, so as to inhibiting frequency splitting phenomenon and improve transmission efficiency. Finally, experiments platform of wireless power transmission system of small size resonator was set up, and the experimental results show that the system can successfully charge the load with good transmission performance, which is suitable for small wireless energy transmission equipment.
