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.

Abstract: The invention provides integrated turbogenerators having a turbine wheel, a compressor impeller, and a motor generator mounted to or mechanically constrained to a common shaft, and improved components and configurations thereof.

Abstract: An onboard diagnostic memory module is configured to plug into the OBD II port and has a real-time clock and power supply, a microprocessor powered from a standard OBD II port, microprocessor operating firmware, and an attached memory (7 MB). In operation, the onboard diagnostic memory module is preprogrammed with data collection parameters through microprocessor firmware by connection to a PC having programming software for the module firmware. Thereafter, the onboard diagnostic memory module is moved into pin connection with the OBD II port of a vehicle. Data is recorded on a “trip” basis, preferably using starting of the engine to define the beginning of the trip and stopping of the engine to define the end of the trip.

Abstract: A power generation system is disclosed. In one embodiment, the power generation system includes a fuel source, a turbogenerator coupled to the fuel source, and a power controller coupled to the turbogenerator. The power controller includes an AC/DC power converter that converts AC power generated by the turbogenerator to DC power on output lines for supplying a DC load. The power controller regulates the fuel to the turbogenerator, independent of a DC voltage on the output lines. A capacitor such as an electrochemical capacitor or a hybrid capacitor, coupled across the output lines, sources power to and/or sinks power from the output lines due to load changes by the DC load. In a further embodiment, the power controller includes an additional DC/DC power converter. In yet a further embodiment, the power controller includes a second additional DC/DC power converter to controllably couple the capacitor to a DC bus.

Abstract: A turbogenerator system including a recuperator and a catalytic combustor employs a preheater located between the turbine outlet and the recuperator low-pressure inlet to heat the low-pressure turbine exhaust. Heat from the turbine exhaust is transferred to a cool high-pressure flow in the recuperator. A recirculation loop employs valves downstream of the recuperator low-pressure outlet to divert the recuperator low-pressure exhaust into the compressor to be recirculated through the recuperator high-pressure side and the catalytic combustor. Reduced start-up times and emissions are achieved by raising the combustor catalyst to its light-off temperature in a shorter period of time.
