Abstract
Systems and methods are provided for a double-ended inverter drive system for a fuel cell vehicle. An electric drive system for a vehicle comprises an electric motor configured to provide traction power to the vehicle. A first inverter is coupled to the electric motor, and is configured to provide alternating current to the electric motor. A fuel cell is coupled to the first inverter to provide power flow from the fuel cell to the electric motor. A second inverter is coupled to the electric motor, and is configured to provide alternating current to the electric motor. An energy source is coupled to the second inverter to provide power flow between the energy source and the electric motor. A controller is coupled to the first inverter and the second inverter, and is configured to provide a constant power from the fuel cell during operation of the electric motor.
