In this paper, the magnetic coupling resonant wireless power transmission system model based on type E power amplifier is analyzed by using the circuit theory. A series of topology simulation circuit based on class E power amplifier is established by using software Saber to verify the transmission performance and transmission efficiency of the system at different frequencies by simulation. The results show that the transmission efficiency of the system is closely related to the system frequency and transmission distance, and the energy transfer effect is the best with the resonant frequency.
