Method for regulating bus voltage and voltage regulation device

摘要

The method involves feeding bus voltage to an input over a communication bus. A rule is set based on variations of bus device voltage from a reference value. Variation of current intensity of current (Isp) supplied by a current source during preset regulation time intervals is continuously adjusted depending on a regulation parameter. Time interval is continuously increased with duration of time unit. The variation of current intensity is continuously adjusted depending on the current intensity of current flowing over voltage connections. An independent claim is also included for a ballast device for providing bus device voltage for a bus device.
