Central power supply for lamp operation devices containing a central PFC/rectification device

摘要

The system has a central rectifier unit (31) with an input side connection for alternating voltage (35) and at least one d.c. output stage (39, 392) and several operating devices (32) for light sources supplied with voltage via the d.c. output stages, whereby the central rectifier unit has a circuit (392, 36) for regulating the voltage, the current and/or the power of the output stage : Independent claims are also included for the following: (A) a method for the central voltage supply of operating devices for light sources (B) and a computer software product for supporting the inventive method.
