WPT system based on resonant network control strategy
In order to improve the working distance range and efficiency of the wireless power transfer(WPT)system,a WPT system scheme based on the resonant network control strategy is proposed.In this solution,the resonant capacitor control circuit and the resonant inductor control circuit are used to realize the adaptive matching of the system′s resonant frequency.Furthermore,by reconstructing the structure of the coil and optimizing the design of the coil structure,the mutual inductance and coupling coefficient at different distances are improved,so that the working distance range and power transmission performance are improved.In order to verify the feasibility of the system solution,it was first verified by means of the magnetic field simulation and circuit simulation,and then the WPT prototype was built for the performance test.The testing results show that in comparison with the general WPT system,the working distance range of the proposed system solution is increased by 50%,and the efficiency within the entire distance range is improved significantly.
