基于磁共振的无线能量传输技术应用环境复杂多变,很难保证收、发线圈的参数和结构保持一致。本文针对发射模块参数不变的情况,研究了接收模块线圈半径、线径、线圈匝数和线圈长度变化对电感、电阻、品质因数、互感、耦合系数和传输效率的影响。理论计算与 Pspice仿真均表明,线圈半径的变化对系统传输效率的影响最大,系统传输效率随着线圈半径的增大而增大,但当接收模块的线圈半径小于发射模块线圈半径的50%时,系统的传输效率迅速降低;增大线圈长度对系统的传输效率影响相对较大,增大线圈长度使系统传输效率先减小后增大;导线半径和线圈匝数的变化对传输效率的影响最小,系统传输效率随着它们的增大而略微增大。

Wireless energy transfer system based on magnetic resonance can be applied in different situations. It is hard to make the structure and parameters of the receiver consistent with the transmitter. The impact of receiver parameters, including coils radius, conductor cross-sectional radius, number of turns, and height of coil on the inductance, resistance, quality factor, mutual inductance, coupling coefficient and transfer efficiency of wireless energy transfer systems based on magnetic resonance are studied with parameters of the transmitter are fixed, respectively. Theory calculations and PSPICE simulation indicate that the power transfer efficiency will increase with the increasing of receiver coils radius, conductor cross-sectional radius, number of turns, and height of receiving coil. The effect of radius of receiver is more significant than other parameters. The transfer efficiency will increase notable with the increasing of radius of receiver coils, while increasing slightly with the increasing of conductor cross-sectional radius, number of turns, and height of receiving coil.
