    摘要:

    为研究不同拾取端对动态无线电能传输系统的影响,首先使用诺以曼公式对互感进行数值分析,以探究耦合机构互感的变化对系统的传输效率和拾取端电压影响;再通过等效电路模型与基尔霍夫方程式,建立动态无线电能传输系统的数学模型,提取出系统传输效率与品质因数、耦合系数、负载和邻近线圈电阻值的关系式;最后通过制作不同拾取端的耦合机构,包括单线圈、串联式和并联式,在动态中对系统传输影响的分析。分析与实验结果相符,证明本文结论的有效性。

    Abstract:

    To study the influences of different pickup ends on a dynamic wireless power transfer(WPT) system, the Neumann formula is used at first to carry out numerical analysis on mutual inductance to explore the influences of changes in the mutual inductance of a coupling mechanism on the system transmission efficiency and the voltage at the pickup end. Through the equivalent circuit model and Kirchhoff equation, the mathematical model of a dynamic WPT system is established, and the relation between the system transmission efficiency and the quality factor, coupling coefficient, load, and nearby coil resistance is extracted. Afterwards, the coupling mechanisms with different pickup ends were fabricated, including types of single coil, serial and parallel, and the influences on system transmission were analyzed under dynamics. Simulation results agreed with the experimental results, which proves the validity of conclusions given in this paper.
