Distance Characteristics of Wireless Power Transfer System Based on Magnetic Resonance Coupling

通过设计磁耦合谐振式无线电能传输试验装置,研究了谐振线圈参数的改变对传输距离的影响。研究结果表明:当谐振线圈的线径以及材质固定时,线圈半径越大,系统电能传输距离越远;当谐振线圈的半径以及材质固定时,线圈线径越大,系统电能传输距离越远;当谐振线圈的半径以及线径固定时,线圈的电导率越大,系统电能传输距离越远;当谐振线圈的所有参数固定时,系统谐振频率越大,电能传输距离越远。

The effects of resonance coil parameters on transfer distance were investigated through experimental device of magneticall coupled resonant wireless power transfer. The results show that the bigger the resonance coil radius,the longer the transfer distance when the wire radius and materials are fixed. The bigger the coil wire radius,the longer the transfer distance when the resonance coil radius and materials are fixed. The higher the conductivity of the coil material,the longer the transfer distance when the coil radius and wire radius are fixed. The higher the resonance frequency is,the longer the transfer distance.
