Abstract: A dual inverter open winding machine for a vehicle. The machine may include an electric motor, a first energy source, a first inverter, a second energy source, and a second inverter. The first inverter may include a plurality of first switches independently operable between an opened position and a closed position to selectively connect and disconnect a first direct current (DC) port and a first alternating current (AC) port with one or more of the first energy source, the first inverter, and the motor. The second inverter may include a plurality of second switches independently operable between an opened position and a closed position to selectively connect and disconnect a second DC port and a second AC port with one or more of the second energy source, the second inverter, and the motor.
