  • Mobile hybrid electric power system
    Patent number: 11444609
    Abstract: A system includes a prime mover configured to rotate a shaft. The system also includes a wound rotor induction generator (WRIG). The WRIG includes a rotor coupled to the shaft of the prime mover and configured to rotate when the shaft rotates, where the rotor includes a rotor winding. The WRIG also includes a stator winding electrically connected to a utility source and a load. When the stator winding receives first power from the utility source, the WRIG is configured to transform at least one of a voltage and a frequency of the first power before outputting at least a portion of the first power to the load. When the stator winding does not receive the first power from the utility source, the WRIG is configured to generate second power due to kinetic energy of the rotor and output at least a portion of the second power to the load.
