Electricity: single generator systems inventions 07/09

20090184691 - Dual purpose permanent magnet exciter: A permanent magnet rotor of a generator is used to excite a permanent magnet stator to generate electric power for the generator and to control a disengagement mechanism whereby the generator can disengage from an accessory, such as a gear box drive shaft, when the generator is not working properly.... Agent: Honeywell International Inc. Patent Services

20090184692 - Acg output voltage control: A system provides generator control for a power system within a vehicle. The system includes a battery, a generator that outputs power to charge the battery. A sensor detects a state of charge (SOC) value, a health value, a voltage, a current, a temperature, and a charging voltage of the... Agent: Fay Sharpe LLP

20090184693 - Acg output voltage control: A generator control system is provided in a vehicle having an engine that drives an electric power generator arranged to selectively provide electric power to an electrical load of the vehicle and to selectively charge a battery of the vehicle. The generator control system includes: a sensor that detects a... Agent: Fay Sharpe LLP

20090167256 - System and method for suppressing dc link voltage buildup due to generator armature reaction: A controller employed in conjunction with a synchronous generator monitors the output voltage of the generator. The controller employs the monitored output voltage as feedback that is used to control the excitation provided to an exciter field winding. In addition, the controller applies a control loop to the monitored output... Agent: Kinney & Lange, P.A.

20090167255 - Voltage regulation to reduce ripple in a power generation system: Methods and systems are disclosed for reducing alternating current ripples in direct current electrical power generation systems with one or more regulated permanent magnet machines. Ripple suppression is achieved, in one aspect, by modulating the control current of a regulated permanent magnet machine.... Agent: Bachman & Lapointe, P.C. (pwc)

20090167257 - Shorted rotating diode detection and protection: An electric generator with a rotating diode fault detection device built in that operates by comparing a voltage buildup across the exciter DC supply with a preset threshold value and determining if a fault condition is present based on the comparison.... Agent: Carlson, Gaskey & Olds, P.C.

20090167258 - Magnetic torsion accelerator: An inexpensive means of using homopolar technology to test some aspects of magnetic shear and reconnection on a variety of solid, liquid, gaseous, and plasma substances... Agent: Michael Peavey
