Abstract

A circuit arrangement is specified for the high-frequency operation of one or more low-pressure discharge lamps connected in parallel with one another. The circuit arrangement has a mains rectifier with a downstream active harmonic filter, a downstream smoothing capacitor and a high-frequency generator allocated to each low-pressure discharge lamp. The high-frequency generator is a single-ended high- frequency generator which has one switching transistor (T1), one switching inductor (L1) and an oscillator capacitor (C1) and which is operated on the smoothing capacitor (C0), decoupled from the mains via two diodes (D5, D6). <IMAGE>
