    This work presents a universal, bidirectional onboard charging structure for electric vehicles, designed for the ability to be connected to any type of residential ac and dc grids with minimized redundancy. Offering true plug-and-play flexibility for global charging infrastructure, the electric vehicle equipped with a universal onboard charger can be charged from single-phase and three-phase ac sources, as well as two-wire and three-wire dc supplies. The bidirectional power flow capability enables both vehicle-to-grid (V2G) and grid-to-vehicle (G2V) operation. The hardware setup rated up to 11 kW was designed and experimentally validated, demonstrating all claimed features.
