Abstract

Circuit arrangement having a converter without a transformer but with an inductor for the pulsed operation of dielectric barrier discharge lampsThe circuit arrangement according to the invention comprises an inductor-type converter for the pulsed operation of dielectric barrier discharge lamps (EL). The invention proposes both a half bridge variant and a full bridge variant. By selecting the inductance value of the inductor (L), it is possible to influence the edge steepness of the pulses, in the case of more than one inductor even independently for the rising and falling edges.
