Patent number: 10779376Abstract: The aim of the invention is to determine an operating point (220) of an AC/DC converter and optionally of a DC/DC converter, fed by the AC/DC converter, for feeding an operating DC voltage into a luminaire bus system in such a way that a power loss (202) of the luminaire bus system is reduced. This aim is achieved according to the invention in that a plurality of calibration DC voltages (282) are sequentially fed into the luminaire bus system, and a corresponding power consumption of the luminaire bus system is determined for each calibration DC voltage (282). The operating point can then be determined based on the power consumptions.Type: GrantFiled: December 18, 2017Date of Patent: September 15, 2020Assignee: TRIDONIC GMBH & CO KGInventor: Günter Marent
