Patent number: 8729844Abstract: An AC-AC power converter supplies AC power to an AC motor having a plurality of motor windings and a case connected to a ground. The AC-AC power converter architecture includes an asymmetric phase shift autotransformer/rectifier unit (ATRU) that converts an AC input to a DC output, wherein the asymmetric phase shift ATRU generates a common-mode AC voltage across the asymmetric phase shift ATRU. The common mode voltage is diverted to ground through motor case parasitic capacitance via a common-mode voltage pull-down circuit connected between each phase of the ATRU AC input and the ground.Type: GrantFiled: January 18, 2012Date of Patent: May 20, 2014Assignee: Hamilton Sundstrand CorporationInventors: Frank Z.

Patent number: 8593808Abstract: An electronics cooling system comprises a tubular fan duct and an electronics housing. The fan duct includes has a fan duct casing containing a fan with rotor blades and stator vanes. The electronics housing is mounted directly on the tubular fan duct, such that the electronics housing and the fan duct casing together enclose an interior space. A cooling airflow path extends from a high-pressure region of the tubular fan duct, through an inlet hole into the interior space, and out a bleed hole into a surrounding environment. The electronics cooling system further comprises three electronics mounts within the interior space. A first electronics mount is located immediately adjacent to the inlet hole, on the fan duct. A second electronics mount is located immediately radially outward of the stator vanes, on the fan duct. A third electronics mount is located immediately adjacent to the bleed hole, on the housing.Type: GrantFiled: September 15, 2011Date of Patent: November 26, 2013Assignee: Hamilton Sundstrand CorporationInventors: Debabrata Pal, Mark W.

Patent number: 8325461Abstract: A feed-through capacitor is constructed in a printed wiring board using alternating layers of metal capacitive layers and plastic dielectric layers of the printed wiring board. The large number of layers, the avoidance of ceramic layers and the flexible geometry of this device allow it to be used in many applications, particularly in those involving high power high current. Also, because it utilizes a printed wiring board, the capacitor can be made in numerous sizes and shapes.Type: GrantFiled: August 8, 2008Date of Patent: December 4, 2012Assignee: Hamilton Sundstrand CorporationInventors: Eugene W.

Patent number: 7538990Abstract: An apparatus, and a method of opening and closing electrical power feed lines using a hybrid contactor, which combines a traditional set of mechanical main contacts with a high voltage solid state switch. The solid state switch provides a parallel current path around the main contacts. When the main contacts are to be opened or closed, the solid state switch is first closed, diverting current away from the main contacts to prevent arc formation when the main contacts are being opened or closed. Once the main contacts are opened or closed, the solid state switch is opened, as the parallel current path is no longer needed. Optional auxiliary contacts are connected in series with the solid state switch to provide galvanic isolation between an input terminal and an output terminal.Type: GrantFiled: December 14, 2006Date of Patent: May 26, 2009Assignee: Hamilton Sundstrand CorporationInventors: Francis C. Belisle, Eric A. Carter, Mark W. Metzler, Jeffrey T. Wavering
