Patent number: 12176705Abstract: The aim of the invention is to detect an arc in an assembly for transmitting a direct voltage. This aim is achieved by a communication transformer having a primary winding and a secondary winding, the secondary winding being connected to a transmitting device, which is designed to impress a communication signal onto the secondary winding of the communication transformer, and the primary winding being connected to one of the direct voltage lines in order to feed a communication signal transformed by the communication transformer to one of the direct voltage lines. In order to detect, in the assembly, the arc signal caused by an arc, the secondary winding is connected to an arc detection unit, which is designed to detect an arc signal transformed by the communication transformer.Type: GrantFiled: September 20, 2023Date of Patent: December 24, 2024Assignee: Fronius International GmbHInventors: Bernd Hofer, Christian Fasthuber, Franz Fischereder, Stefan Breuer, Walter Spitzer, Mario Bairhuber, Reimar Pfeil

Patent number: 11831149Abstract: To recognize a fault in an arrangement including a transformer having a primary winding connected in series with a DC voltage line and a secondary winding coupled magnetically to the primary winding, and including an evaluation unit that processes a secondary signal on the secondary winding, a signal component at at least one frequency is determined from the secondary signal and a signal level of the signal component is compared with a signal threshold. The fault is detected when the signal level falls below the signal threshold.Type: GrantFiled: September 26, 2019Date of Patent: November 28, 2023Assignee: FRONIUS INTERNATIONAL GMBHInventors: Bernd Hofer, Stefan Breuer, Christian Fasthuber, Walter Spitzer, Andreas Hofer
