Patent number: 11791621Abstract: A method includes detecting a failure in a contactor economizer that is configured to provide a first current to a coil of a contactor to close the contactor, and to provide a second current lower than the first current to the coil after the contactor is closed to hold the contactor closed. The method includes at least one of: driving contactor actuation based on economizer failure status; and/or signaling failure of the economizer through built in test (BIT) indication.Type: GrantFiled: March 17, 2020Date of Patent: October 17, 2023Assignee: Hamilton Sundstrand CorporationInventors: Jordan K. Vanevenhoven, Thomas P. Joyce, Natalie Filipski

Patent number: 11705296Abstract: A system includes a contactor operatively connected to a coil for actuating the contactor to open and close a circuit. A pass element includes a source, a drain, and a gate, wherein the drain is electrically connected to the coil, and wherein the coil is in series between the pass element and ground. A voltage source is connected to the source of the pass element to pass current into the coil when the pass element is in a pass state. A current source control circuit with economizer is operatively connected to the gate of the pass element. A delay circuit is operatively connected to the current source control circuit with economizer and to a command line to command a lower current for holding the contactor closed after a delay has expired for the contactor to transition.Type: GrantFiled: May 26, 2022Date of Patent: July 18, 2023Assignee: Hamilton Sundstrand CorporationInventors: Thomas P. Joyce, Jordan K. Vanevenhoven, Natalie Filipski

Patent number: 11329539Abstract: A system including a generator and a controller. The generator includes a permanent magnet generator (PMG), and an exciter. The controller manages operations of the generator. The controller includes an alternating current to direct current (AC-to-DC) converter that generates a direct current (DC) voltage, an exciter drive that provides a DC current to the exciter of the generator using the DC voltage created by the AC-to-DC converter in accordance with the control signal, and a regulator controller that drives the active AC-to-DC converter.Type: GrantFiled: March 11, 2020Date of Patent: May 10, 2022Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Adrian E. Vandergrift, Thomas P. Joyce, Jordan K. Vanevenhoven, Natalie Filipski

Patent number: 11133672Abstract: A system for connecting first and second high voltage direct current (HVDC) sources in parallel to a bus includes one or more contactors connecting the first HVDC source to the bus. The system also includes a bus coupling circuit located between the second HVDC source and the bus that utilizes inductors to couple, in operation, couples the second HVDC source to the bus such that first and second HVDC sources are in parallel with the second positive output is connected to the positive rail and the second negative output connected to the negative rail. The inductors are first connected to the bus though auxiliary contactors and, after a predetermined time, main contactors are closed that provide a path around the inductors.Type: GrantFiled: March 6, 2020Date of Patent: September 28, 2021Assignee: HAMILTON SUNDSTRAND CORPORATIONInventors: Thomas P.
