Illumination system has electronic transformation stage connected across energy supply line supplied by current supply stage for providing HF operating voltage for lamp

摘要

The illumination system has a current supply stage (B1) containing a filter circuit ((FC) supplied from an AC source and coupled to an energy supply line across which at least one electronic transformation stage (A1) with a rectifier (DB) and an inverter (1), is connected for providing a HF output voltage for operation of a lamp (3).
