US Patent:

7405496, Jul 29, 2008

Filed:

Jan 27, 2004

Appl. No.:

10/766603

Inventors:

Robert Gregory Wagoner - Roanoke VA, US
Scott Charles Frame - Schenectady NY, US
Brian Eric Lindholm - Salem VA, US
Pedro Monclova - Salem VA, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

H02J 1/00

US Classification:

307 82, 307 85

Abstract:

A method and transfer circuit topology for a redundant power converter for switching a load between power conversion circuits in a redundant system. The transfer circuit topology includes a first contactor and a second contactor each having an input coupled to a source and an output coupled to a controlled commutating current path. The controlled commutating current path is coupled to the load for switching between the redundant power converters without interrupting current to the load.

International Classification:

F03D 9/00
H02P 9/00

US Classification:

290 44, 322 44

Abstract:

An integrated fault and personnel protection system and method for a multi-thread converter in a wind turbine power system is provided. The structure and method provide for system optimization, as well as, arc flash protection. Fault sensing with means of removing power applied to the converter minimizes the energy available to produce an arc flash event. Sensing and disconnects devices for the protections are provided close to the source of energy to protect more of the system. Converter controls detect, identify and isolate faults selecting the best combinations of the novel specific fault isolation devices. Components are distributed into separate physical to enhance protection.

Appl. No.:

12/971810

Inventors:

Huibin Zhu - Westford MA, US
Allen Ritter - Roanoke VA, US
Scott Charles Frame - Boones Mill VA, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

H02M 7/5387

US Classification:

363132

Abstract:

A power converter system includes an inverter including a first bridge and a second bridge, wherein each of the first bridge and the second bridge includes at least one switch.

Appl. No.:

13/470550

Inventors:

Robert Gregory Wagoner - Roanoke VA, US
Scott Charles Frame - Boones Mill VA, US
Chunchun Xu - Boones Mill VA, US
Huibin Zhu - Westford MA, US

International Classification:

H02M 7/5387

US Classification:

363132

Abstract:

In one aspect, a method of converting power is described. One embodiment of the method comprises receiving direct current (DC) power; channeling the DC power through an inverter including a first bridge and a second bridge, wherein each of the first bridge and the second bridge includes at least one switch; controlling the at least one switch of the first bridge and the at least one switch of the second bridge to convert the DC power to alternating current (AC) power; and, channeling the AC power through an inductor that includes a first winding and a second winding, wherein the first winding is coupled to an output of the first bridge and the second winding is coupled to an output of the second bridge and wherein the inductor is configured to have a first magnetic path for common mode inductance and a second magnetic path for differential mode inductance.

US Patent:

42508169, Feb 17, 1981

Filed:

Dec 16, 1976

Appl. No.:

5/751118

Inventors:

John S. Angevine - Pittsburgh PA
Scott W. Frame - Anniston AL
Stephen B. Yacura - Glenshaw PA

Assignee:

Pullman Incorporated, Pullman Swindell Division - Pittsburgh PA

International Classification:

F23K 302

US Classification:

110101CF

Abstract:

The application discloses a particulate solid fuel combustion system for kilns and the like. A particulate solid fuel such as powdered coal, is supplied to a fluidized bed conveyor. Selected quantities of coal are withdrawn to air entrainment devices where the coal is entrained in a jet of a gas and delivered to a burner. The firing rate is controlled responsive to requirements of the kiln.
