Circuit arrangement for operating discharge lamps In the case of circuit arrangements for operating gas- discharge lamps (Lp), a charge pump (D5, D6, C31, C32) is often used for the purposes of power-factor correction. If this is the case, poorly igniting lamps (Lp) experience an increase in voltage across a storage capacitor (C1). This is avoided according to the invention by a PTC (KL) in parallel with diodes (D5, D6) of the charge pump.
