Abstract:
Based on the design requirements of high frequency power amplifier for magnetic coupling resonant wireless power transfer system,the issue should be taken seriously that the soft-switching of class E power amplifier affected by the load. Having considered it,this paper proposes a magnetic coupling resonant wireless power system combined with the Class E power amplifier,which can achieve the constant current and the constant voltage charging of lithium batteries. The simulation and experimental results show that the parameters of the proposed system are designed well,which can ensure soft-switching of the class E power amplifier with the load independent.
