Abstract:
Electronic operating device for gas discharge lamps which has the following features:an AC voltage generator (G) which makes an AC voltage available between a generator output (1) and a reference potential (E), a reactance network (Z) which is connected to the generator output (1) and which provides a first output terminal (2) to which one or more series-connected discharge lamps (LP) are connected, a series circuit of a coupling capacitor (CB) and an electric component (VC) via which the lamp circuit is connected from a second output terminal (3) to the reference potential (E), and a reduction voltage (UVC) which is formed at the two poles of the electric component (VC), the voltage profile of the reduction voltage (UVC) being characterized in that it reduces the root-mean-square value of the voltage between at least one output terminal (2, 3) and the reference potential (E).
