The control device measures a duty cycle of a generator output power controller to ascertain the generator power level and generates a signal to a prime mover controller so that the generator duty cycle remains within a pre-determined range. The power control system may include a transmission wherein the control device operation may be conditioned on a state of the transmission. The power control system may include a speed converter coupled with the prime mover wherein the control device converts a speed of the prime mover according to the generator power level. The control device may operate to control an output power of the generator concurrently with controlling the output power of the prime mover.Type: GrantFiled: August 18, 2008Date of Patent: April 6, 2010Assignee: C. E. Niehoff & Co.Inventors: Issam Jabaji, Shadi Jabaji

Patent number: 7692414Abstract: The present invention provides for a static excitation system for a superconducting rotor that comprises multiple brushes (12) in contact with the superconducting rotor winding (6), normally via collector rings and field leads. A power conditioning device (16) is connected to the brushes (12), and an energy storage device (18) is linked to the power conditioning device (16). The power conditioning device provides power from the energy storage device to the superconducting rotor when required, and when power to the superconducting rotor is not required, the power conditioning device takes excess power from the superconducting rotor and stores it in the energy storage device.Type: GrantFiled: June 14, 2007Date of Patent: April 6, 2010Assignee: Siemens Energy, Inc.Inventor: Robert J.

Patent number: 7692417Abstract: A voltage converter having a controller capable of maintaining stable operation of a voltage converter over multiple modes of operation. The voltage converter provides a feedback signal to an error signal generator. One or more controllers, which are selectively established as part of the feedback loop, process the error signal to generate a voltage converter charging cycle control signal. A pulse width modulator may be utilized to generate a voltage converter switch control signal that controls the charge cycle. A detector or comparator monitors one or more aspects of operation of the control circuit or the voltage converter to detect changes in the mode of operation. Upon detection of a change, the detector or comparator generate a multi-mode control signal to selectively switch one or more sub-controllers into or out of the feedback loop to thereby maintain desired stability, loop bandwidth, and response time.Type: GrantFiled: September 19, 2005Date of Patent: April 6, 2010Assignee: Skyworks Solutions, Inc.Inventor: Elias Hani Dagher

Patent number: 7692419Abstract: A system and method for enhanced frequency measurement. Embodiments provide an effective mechanism for reducing error associated with frequency measurements by amplifying the frequency of the signal fed to the frequency counter, thereby increasing the number of counts and reducing the error associated with each frequency measurement. Reductions in error enable the gate time for the frequency counter to be reduced, thereby increasing efficiency and cost-savings. After accessing the counts provided for the amplified frequency, the original frequency before amplification may be determined by reducing the amplified frequency (e.g., represented by the accessed counts) by the amount by which the original frequency was amplified. Embodiments provide an effective and efficient mechanism for automatically determining the amount of amplification for a given signal based upon its frequency and a maximum frequency of at least one of the frequency amplification component and the frequency counter.Type: GrantFiled: September 26, 2006Date of Patent: April 6, 2010Assignee: Cypress Semiconductor CorporationInventor: John Peel

Patent number: 7692420Abstract: The current in a conductor is measured by exploiting the Faraday effect in a sensing fiber. The light returning from the sensing fiber is split into at least two parts, at least one of which is analyzed by a first circular analyzer for generating a first signal. A second part may e.g. be analyzed by a second circular analyzer, and a third part may be analyzed by a linear analyzer. By combining the signals obtained in this way, the current induced phase delay in the returning light can be measured efficiently and accurately.Type: GrantFiled: October 22, 2008Date of Patent: April 6, 2010Assignee: ABB Research Ltd.Inventors: Klaus Bohnert, Andreas Frank, Hubert Brandle
