摘要
针对磁共振模式无线电能传输系统功率和效率计算问题,利用互感耦合模型,对磁共振模式电能传输系统的4种拓扑进行分析,得出了系统的传输功率及其计算模型,并进一步分析了系统传输效率与线圈谐振频率、互感系数、线圈内阻等参数之间的关系,为磁共振模式无线电能传输系统的设计及参数优化提供了理论依据。为验证理论分析的正确性,制作了一个磁共振模式无线电能传输装置,该装置实现了80 cm内60 W的无线能量传输,且传输效率达到了52%。
In order to solve the problem of the calculation of the power value and its efficiency of the magnetic resonance wireless power transmission system,based on the mutual inductance coupling mode,the calculation model for the transmission power and its efficiency of the system was given through analyzing the system with four different topologies.And further analysis of the relationship between the system transmission efficiency and resonant frequency of the coil,mutual inductance,coil resistance and other parameters was given too,which can provide the theoretical basis for the design and energy optimization of the system.A magnetic resonance mode of wireless power transmission system equipment was designed to verify the theoretical analysis.The equipment can transfer 60？W of wireless power through a distance of 80 cm,and the transmission efficiency is 52%.
