    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.

    Abstract: Systems and methods are provided for pulse-width modulated control of power inverter using phase-shifted carrier signals. An electrical system comprises an energy source and a motor. The motor has a first set of windings and a second set of windings, which are electrically isolated from each other. An inverter module is coupled between the energy source and the motor and comprises a first set of phase legs coupled to the first set of windings and a second set of phase legs coupled to the second set of windings. A controller is coupled to the inverter module and is configured to achieve a desired power flow between the energy source and the motor by modulating the first set of phase legs using a first carrier signal and modulating the second set of phase legs using a second carrier signal. The second carrier signal is phase-shifted relative to the first carrier signal.

    Abstract: Methods and systems for controlling a power inverter in an electric drive system of an automobile are provided. A signal controlling the power inverter is modified utilizing a first voltage distortion compensation method if a modulation index of the signal is less than a first modulation index value. The signal is modified utilizing a second voltage distortion compensation method if the modulation index is at least equal to the first modulation index value.
