Publication number: 20220186647Abstract: A heating device for an exhaust system has an electrically conductive foamed part and at least one stabilization part for the foamed part. The foamed part includes two end faces, an outer circumference and at least one recess starting from the outer circumference and extending in the axial direction from one to the other end face. The recesses produce sections which are opposite each other at a distance and continue into each other, forming a current path as a resistance heating element. The stabilization part at least partially fills the recess and mechanically couples the sections to each other, but does not electrically couple them to each other.Type: ApplicationFiled: November 30, 2021Publication date: June 16, 2022Inventors: David Saurat, Yannick Fourcaudot, Christophe Basso, Jean-Francois Perret, Jura Kautz, Claudia Herbers, Jörg Veittinger, Matthias Mallon

Patent number: 10164540Abstract: A controller for a power conversion circuit has a first current-reading circuit coupled for receiving a first feedback signal at a first circuit node and generating an internal feedback signal at a second circuit node inversely proportional to the first feedback signal. A second current-reading circuit is coupled for receiving a second feedback signal at the first circuit node and generating the internal feedback signal at the second circuit node inversely proportional to the second feedback signal. The first current-reading circuit generates the internal feedback signal inversely proportional to an electric current injected into the controller at the first circuit node. The second current-reading circuit generates the internal feedback signal inversely proportional to an electric current drawn from the controller at the first circuit node.Type: GrantFiled: June 14, 2016Date of Patent: December 25, 2018Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Christophe Basso, Stephanie Cannenterre
