| description | This article proposes and implements a selective wireless power transfer (WPT) system based on magnetic field editing technology. Compared with the traditional WPT without control of power regions, the proposed system can deliver the energy with higher safety, flexibility, selectivity, and can be applied to multiple receivers. The algorithms for current calculation and synchronized control strategies are given to construct the desired magnetic field effectively. The optimization process based on the receiver configuration and voltage threshold is also demonstrated. Both simulation and experimental results validate that the magnetic field distribution can be arbitrarily edited through the proposed current control strategy, and realize the selectivity of the powering area. A prototype of the proposed system with five transmitters is constructed and tested, which can successfully deliver wireless power of 14 W over the distance of three times larger than the radius of the receiver coil with the transmission efficiency over 79%. |
