A circuit arrangement for operating discharge lamps is provided with an input, to which an AC system voltage from a power supply system can be connected, an output, to which at least one discharge lamp can be connected, a backup capacitance, which is arranged between the input and the output, and a switch, which is in a charging current path of the backup capacitance. The circuit arrangement may include a driver configured to clock the switch for a predetermined period of time when the circuit arrangement is switched on for periodically interrupting the charging current path of the backup capacitance. |
