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 (j,j,), a load circuit which is connected to the alternating voltage output (j,j,) and which has at least one lamp inductor (L,), a coupling capacitor (C,) and terminals (j,j,) for at least one high-pressure discharge lamp (LP), and a starter (Z) with a high-voltage source and a high-voltage DC output (j,j,) for starting a gas discharge in the at least one high-pressure discharge lamp (LP). The coupling capacitor (C,) is connected to the high-voltage DC output (j,j,) via a charging resistor (R,).
