Abstract This paper uses circuit theory and calculation of mutual inductance between the transmitting and receiving coil to model and simulate the characteristics of the magnetic coupling resonant wireless power transmission system.It studies the influence of the transmitting and receiving coil inductances on the transmission characteristics.Based on that,this paper establishes the relationship between the transmission distance as well as the resonant frequency and transmission characteristics including the load power and the transmission efficiency,which provides a theoretical basis for the design of detailed parameters of the resonant circuit.Then,the analysis of the broadband class-E power amplifier provides a solution to maintain higher system efficiency in wide band working condition.Finally,the theoretical derivation and the simulation are verified by the experimental analysis.
