20090079399 - Overload control of an electric power generation system: A control system for an electrical power generation system (EPGS) provides overload protection without disconnecting a generator of the EPGS from an excessive electrical load. Available engine power and current levels of the electrical load are continuously measured. A command voltage is calculated that corresponds to a voltage required to... Agent: Honeywell International Inc.

20090079400 - System and method for electric current and power monitoring and control of a generator: A control device measures a voltage drop across a conductor in a generator to determine and control the total generator output current. A temperature of the conductor is also measured to improve the accuracy. The control device may further improve on the accuracy by compensating for the electrical current through...

20090072797 - Load-off transient acceleration generator control system: An electric generator is operated under conditions in which rapid off-loading may occur. A generator control unit (GCU) employs a detector to detect rates of change of output of the generator. In response to a rapid change of output, e.g. an off-loading, an overvoltage protection system is activated. Excess energy... Agent: Honeywell International Inc.

20090066298 - electrostatic generator/motor: A sub-module consists of a set of two outer sets of stationary fan-blade-shaped sectors. These outer sectors include conductive material and are maintained at ground potential in several examples. Located midway between them is a set of stationary sector plates with each plate being electrically insulated from the others. An... Agent: Lawrence Livermore National Security, LLC

20090066297 - Power generation apparatus using ac energization synchronous generator and method of controlling the same: A power generation apparatus and method includes an AC energization synchronous generator, a switching device which connects to a network disposed on a stator side of the AC energization synchronous generator, an energizing device which applies a variable frequency AC to a secondary winding of the AC energization synchronous generator,... Agent: Antonelli, Terry, Stout & Kraus, LLP

20090058372 - Voltage controller for vehicle using averaged status signal: In a voltage controller for a vehicle, voltage controlling means controls an output voltage of a power generator mounted on the vehicle and a terminal voltage of a battery connected to the power generator, by controlling of a field current passing through a field winding of the power generator. This... Agent: Oliff & Berridge, PLC

20090058373 - Generator control circuit: A generator control circuit is disclosed. One embodiment provides a first active switching circuit configured to connect a first terminal of an excitation coil either to a first or to a second terminal of a voltage source, a second active switching circuit configured to connect a second terminal of the... Agent: Dicke, Billig & Czaja

20090058374 - High efficiency alternator: A high efficiency alternator capable of supplying extreme high power output with maximum dissipation of heat. Preferably, the alternator includes dual field coils mounted stationary around a common shaft and dual brushless rotors. The alternator may also include three or more phases, and uniquely wound stator assemblies. The alternator may... Agent: Michael P. Mazza, LLC
