Abstract:
A circuit arrangement for operating at least one high-pressure discharge lamp with a high-frequency alternating voltage, the circuit arrangement comprising: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 for at least one high-pressure discharge lamp (LP),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),wherein the coupling capacitor (C1) is connected to the high-voltage DC output (j14, j15) via a charging resistor (R1).
