Abstract
The invention relates to a circuit arrangement for operating electric lamps (), in particular dielectric barrier discharge lamps, having an input stage () in the form of a voltage-increasing converter, in particular a step-up converter, and at least one subsequent further circuit stage (), for example a flyback converter in the form of a pulse stage. An intermediate circuit overcurrent protection device () is connected between the step-up converter () and the flyback converter () and protects the flyback converter () in the event of a fault, specifically in particular if the input overcurrent protection device () does not respond.
