Patent
CA 2490485
The invention relates to a circuit arrangement for operating electric lamps (5), in particular dielectric barrier discharge lamps, having an input stage (1) in the form of a voltage-increasing converter, in particular a step-up converter, and at least one subsequent further circuit stage (2), for example a flyback converter in the form of a pulse stage. An intermediate circuit overcurrent protection device (3) is connected between the step-up converter (1) and the flyback converter (2) and protects the flyback converter (2) in the event of a fault, specifically in particular if the input overcurrent protection device (1) does not respond.
