Abstract: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%.
Keywords:mutual inductance coupling  magnetic resonance mode  resonant frequency  mutual inductance  coil resistance  parameter optimization
