摘要
An apparatus includes a controller, a switching block, and a three-phase bidirectional AC/DC converter. The switching block has a first interface connected to a power grid, a second interface connected to an electric motor, and a third interface connected to the three-phase bidirectional AC/DC converter that includes first, second, and third single-phase AC/DC conversion modules, and which have inputs and outputs joined at an output node, and a respective transformer configured to provide electrical isolation. In a first mode of operation, the switching block connects the power grid to the AC/DC converter for charging a battery connected to the output node and disconnects the electric motor. In a second mode of operation, the switching block disconnects the power grid and connects the electric motor to the AC/DC converter which is controlled to convert DC power drawn from the battery to energize the electric motor.
