Patent ID: 8063580

Claim:
A circuit arrangement for driving a high-pressure gas discharge lamp, comprising: a first terminal for a first voltage potential, a second terminal for a second voltage potential, a third terminal for applying a third voltage potential for igniting the high-pressure gas discharge lamp, a first electrical connection, which at its first end provides a first connection terminal for a high-pressure gas discharge lamp and which is coupled at its second end to the first terminal the first voltage potential, a second electrical connection, which at its first end provides a second connection terminal for a high-pressure gas discharge lamp and which is coupled at its second end to the second terminal for the second voltage potential, an ignition device, which at its input side is connected at least to the third terminal and is coupled at its output side to one of the terminals for the high-pressure gas discharge lamp, a first inductor arranged in the first electrical connection, as well as a second inductor arranged in the second electrical connection that forms a current-compensated choke through magnetic coupling with the first inductor that serves to reduce the interfering pulses appearing at the first terminal for the first voltage potential and at the second terminal for the second voltage potential, and an electrical resistor having a resistance value that is at least half an impedance of the inductors in a frequency range between 50 MHz and 150 MHz arranged in a third electrical connection between the ignition device and the third terminal and serves to reduce the interfering pulses appearing at the third terminal.
