Abstract

A circuit arrangement for operating at least one high-pressure discharge lamp with a high-frequency alternating voltage, the circuit arrangement having a voltage converter (W) with an alternating voltage output (j10, j11), a load circuit which is connected to the alternating voltage output (j10, j11) and which has at least one lamp inductor (L1), a coupling capacitor (C1) and terminals (j12, j13) for at least one high-pressure discharge lamp (LP), and a starter (Z) with a high-voltage source and a high-voltage DC output (j14, j15) for starting a gas discharge in the at least one high-pressure discharge lamp (LP). The coupling capacitor (C1) is connected to the high-voltage DC output (j14, j15) via a charging resistor (R1).
