摘要
利用耦合模理论与传统的电路互感理论对谐振式无线能量传输系统进行建模分析。阐述了谐振式无线能量传输系统在传输过程中的能量变化及传输机理。本文通过对比基于两模型的谐振式无线能量传输系统下效率、功率、能量变化等参数并进行Matlab仿真,结果表明:两种模型在计算系统的稳态参数包括传输效率、功率等具有等效性;当系统处于近场耦合,系统具有高品质因数且系统互感耦合系数很小时,耦合模理论模型和电路理论模型才具有等效性。
This paper used coupled mode theory and theory of mutual induction to model the resonant wireless power transmission system.It introduces the variation of energy in the process of transmission and transmission mechanism of the resonant wireless power transmission system.By comparing the parameters of efficiency,power,energy variation according to the two mathematical models and use MATLAB simulating,we find that the two kinds of models are identical in calculation of steady-state parameters such as transmission efficiency,power,but only when the system with high-Q and low mutual coupling factor is coupled in the near-field,the transient response of the system based on the two models are identical.
