摘要
磁谐振耦合式无线能量传输技术因在中等距离范围内能够高效传输较大的功率而受到广泛关注。对基于磁谐振耦合的四线圈结构无线能量传输系统的特性进行分析,通过反射阻抗建立了传输系统的等效电路模型,分析在不同耦合状态下系统的传输效率与传输距离的关系,并在此基础上,利用无线能量传输装置对建模分析的结果进行实验验证。
The technology of magnetic coupled resonance based wireless power transfer （WPT）is paid more attention due to the ability of transmitting more power effectively in the medium range. This paper mainly discusses the four-coil wireless power transfer system which is based on magnetic coupled resonance. Based on the equivalent circuit model of the WPT system by reflecting impedance, and the relationship between transmission efficiency and the transmission distance is analyzed under different coupling conditions. Moreover, the prototype of a WPT system is used to validate the theoretical analysis.
