This thesis is devoted to designing a wireless power-sharing platform with the capability of flexible power supply for electric vehicles charging applications. The primary theme of this research is to provide the power from the vehicle of excessive energy to the one with insufficient energy via the power-sharing platform under the same architecture, hence improving the capability of flexible power supply. To ensure the quality of charging, the system is designed to come with the constant voltage output. The study first investigates different resonance compensation architecture, by which the resonance characteristics of modular expansion and power-sharing operation modes are analyzed. This is followed by the determination of circuit design and coil structure based on the aforementioned analysis, with which the coupling feature and device parameters are prudently assessed. The hardware implementation of the overall system is subsequently realized with the design of feedback control. To verify the feasibility of this proposed method, the completed wireless power-sharing platform of this study is tested under different scenarios. Test results indicate that the system operated in both modular expansion and power-sharing modes exhibits the satisfactory capability of power transfer, which may serve as a beneficial reference for the research and development of electric vehicle industries.
