Design and analysis of magnetic coupling resonant wireless power transfer system with Class-E inverter

Magnetic coupling resonant Wireless Power Transfer (WPT) System is widely used in the medium distance field as a novel technology. This paper presents a WPT system with a proper Class-E inverter structure. In order to solve the problem of the frequency splitting in WPT system. A method is proposed in the system to trace the emission frequency and the receive frequency and control the frequency. Finally, the simulation and experimental results validate the effectiveness of the proposed control algorithms. In the end, simulation experimental results are shown to confirm the effectiveness of the proposed method.
