Patent number: 9153380Abstract: A ceramic short circuit resistant capacitor that is bendable and/or shapeable to provide a multiple layer capacitor that is extremely compact and amenable to desirable geometries. The capacitor that exhibits a benign failure mode in which a multitude of discrete failure events result in a gradual loss of capacitance. Each event is a localized event in which localized heating causes an adjacent portion of one or both of the electrodes to vaporize, physically cleaning away electrode material from the failure site. A first metal electrode, a second metal electrode, and a ceramic dielectric layer between the electrodes are thin enough to be formed in a serpentine-arrangement with gaps between the first electrode and the second electrode that allow venting of vaporized electrode material in the event of a benign failure.Type: GrantFiled: January 29, 2013Date of Patent: October 6, 2015Assignee: Delphi Technologies, Inc.Inventors: Ralph S.

Publication number: 20150171578Abstract: An electrical assembly that includes an electronic device, a buss bar, and an electrical connection. The electronic device is operable to control electrical energy. The buss bar is configured to distribute electrical energy within the assembly. The electrical connection is configured to electrically interconnect the device and the buss bar. The electrical connection is formed of braided wire. Flat braided wire is advantageous as it is more flexible than a direct connection formed by a sheet-metal type lead frame, and provides for large contact areas capable of carrying higher currents than a wire-to-surface type contact made with a twisted wire that is generally round in shape.Type: ApplicationFiled: December 13, 2013Publication date: June 18, 2015Applicant: DELPHI TECHNOLOGIES, INC.Inventors: RALPH S.

A method of forming an endcap of a capacitor configured to interconnect one or more layers of conductive material includes the step of applying conductive nano material to exposed conductive surfaces of at least one of an anode and a cathode of the one or more layers of conductive material. The method also includes the step of exposing the nano material to a source of energy effective to initiate self-sintering of the nano material.Type: ApplicationFiled: July 1, 2014Publication date: March 12, 2015Inventor: RALPH S.

Patent number: 8407871Abstract: A method that employs a novel combination of conventional fabrication techniques provides a ceramic short-resistant capacitor that is bendable and/or shapeable to provide a multiple layer capacitor that is extremely compact and amenable to desirable geometries.
