不同拾取端的动态无线电能传输系统研究

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。

Study on Dynamic Wireless Power Transfer System with Different Pickup Ends

In order to study the influence of different picking ends to dynamic wireless power transfer system, the characteristic formula was first used to carry out numerical analysis on mutual inductance, in order to explore the change of mutual inductance of coupling mechanism, and to influence the transmission efficiency of the system and the voltage of picking end. Through the equivalent circuit model and Kirchhoff equation, the mathematical model of the dynamic wireless power transfer system is established, and the relation between transmission efficiency and quality factor and coupling coefficient is extracted. After that, the coupling mechanism of different picking ends, including single coil, serial and parallel, is made to analyze the influence of system transmission of dynamic. The simulation results agree with the experimental results and prove the validity of the conclusion.
