  • Publication number: 20060066112
    Abstract: A turbogenerator/motor controller with a microprocessor based inverter having multiple modes of operation with an energy storage and discharge system including an ancillary electric storage device, such as a battery, connected to the generator controller through control electronics. Electrical energy can flow from the ancillary electric storage device to the turbogenerator controller during start up and increasing load and vice versa during self-sustained operation of the turbogenerator. When utility power is unavailable, the ancillary electric storage device can provide the power required to start the turbogenerator. When a load transient occurs, the gas turbine engine and the ancillary electric storage device provide the power required to successfully meet the transient.

  • Publication number: 20020157881
    Abstract: A power generation system for a hybrid electric vehicle is disclosed. The system includes a fuel source, a turbogenerator coupled to the fuel source, and a power controller. The power controller is electrically coupled to the turbogenerator, and includes first and second power converters. The first power converter converts AC power from the turbogenerator to DC power on a DC bus, and the second power converter converts the DC power on the DC bus to an operating DC power on output lines. The power controller regulates the fuel to the turbogenerator, independent of DC voltage on the DC bus. The system further includes an electric motor, a drive control unit coupled between the output lines and the electric motor, and a traction battery. The traction battery is coupled across the output lines, and provides an additional source of current, upon demand, to the electric motor.

  • Publication number: 20020149206
    Abstract: A continuous power supply may include a turbogenerator to provide power to supply the load and or an energy storage element and possibly also to the primary energy source. Utilizing an isolated DC bus architecture permits bi-directional power flow among interconnected elements.
