采用COMSOL Multiphysics 软件,对含有多中继线圈结构的无线电能传输系统建模并分析.多中继线圈无线电能传输系统中,随着中继线圈个数的增加,系统传输功率和效率的最佳传输距离随之增加,但其功率和效率值逐渐减小,系统谐振频率发生频率偏移,在近距离会发生明显的频率分裂现象.研究结果表明,在临界耦合距离下,保持各线圈均匀放置在传输系统中,具有较高的功率和效率值.在实际的应用中,要根据需要增加线圈个数,合理设置传输距离这一关键参数.
Analysis of Wireless Power Transfer Characteristics with Multiple Relay Coils based on COMSOL
By using COMSOL Multiphysics software COMSOL Multiphysics software,the wireless power transfer system with multi-relay coil structure is modeled and analyzed.The results show that with the increase of the number of realy coils,the optimal transmission distance of the transmission power and efficiency increases,but the power and efficiency decrease gradually.The resonant frequency of the system will have frequency deviation,and the frequency splitting phenomenon will occur in the near distance.At the critical coupling distance,keeping each coil evenly placed in the transmission system can achieve higher power and efficiency values.In the actual application,the number of coils should be increased according to the need,and key parameter of transmission distance should be set reasonably.
