Abstract:
1. A circuit arrangement for operating a discharge lamp with a dielectric layer between at least one electrode and one discharge medium, comprising: a primary circuit, which comprises a flux converter with at least one electronic switch, the flux converter having a first input terminal and a second input terminal for connecting an input voltage; a secondary circuit, which has a first output terminal and a second output terminal for connecting the discharge lamp; a transformer coupling the primary circuit to the secondary circuit, the transformer having at least a primary winding, a secondary winding and a transformer core, on which the primary winding and the secondary winding are wound; a discrete inductance with a core, the discrete inductance being coupled electrically in parallel with the secondary winding; and the discharge lamp; wherein the discharge lamp corresponds to a parallel circuit comprising a first capacitance and a series circuit, with the series circuit comprising a second capacitance and a nonreactive resistance, the characteristic frequency being lower than 10 kHz, where L represents an unsaturated discrete inductance, and C
