Publication number: 20240014648Abstract: 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: ApplicationFiled: September 20, 2023Publication date: January 11, 2024Applicant: Fronius International GmbHInventors: BERND HOFER, CHRISTIAN FASTHUBER, FRANZ FISCHEREDER, STEFAN BREUER, WALTER SPITZER, MARIO BAIRHUBER, REIMAR PFEIL

Publication number: 20220376475Abstract: A photonic integrated circuit device includes a lasing cavity for resonating at a plurality of discrete wavelengths and an optical feedback cavity operably coupled to the lasing cavity via a front surface of the lasing cavity. The optical feedback cavity has a reflective element for reflecting light, at least partially, back into the lasing cavity to form a resonant Fabry-Perot cavity between the front surface and the reflective element. The optical feedback cavity includes a variable phase shifting element adapted for receiving an input signal to control a phase shift of light propagating in the optical feedback cavity. The amount of light entering the lasing cavity from the optical feedback cavity is low enough to avoid dynamic instability of the lasing cavity. The reduction in light is obtained using an attenuator.Type: ApplicationFiled: October 8, 2020Publication date: November 24, 2022Inventors: Robert PAWLUS, Martin VIRTE, Hugo THIENPONT, Stefan BREUER
