Popis:	Electric vehicles (EVs) that offer grid services using the vehicle-to-grid (V2G) concept essentially require an interface that allows for directional power flow. This article presents a wireless bidirectional grid power interface for EVs that facilitate power flow between the grid, EV, and homes with nonlinear loads. The proposed wireless vehicle-to-grid-to-home power interface (WVGH-PI) uses the grid-side low frequency to dc converter, used in typical wireless bidirectional chargers only to facilitate the two-way energy flow, to improve the power quality by compensating for the harmonic power and reactive power of nonlinear household loads. To improve the overall efficiency of the interface, an adaptive dc-link voltage controller is also proposed. Operation of the proposed wireless interface is investigated under dynamic conditions and in different modes. The simulation and experimental results obtained from a 1-kW prototype are presented, benchmarking against conventional control, to demonstrate the validity of the proposed concept.
