Embodiment Construction
[0037] figure 1 A circuit arrangement known per se for operating a high-pressure discharge lamp is shown, said circuit arrangement having a half-bridge with series-connected half-bridge switches S2 and S3, at the center point of which a lamp choke is connected The series circuit of coil L3, secondary coil L2 of transformer TR and high-pressure discharge lamp 5 is ignited. The free end of the high-pressure discharge lamp 5 is connected to the connection point of the series circuit of two coupling capacitors C1 and C2. The half-bridge is connected in parallel with a series circuit of coupling capacitors. A supply voltage U_B (425 V in this exemplary embodiment) is applied to the parallel circuit. The ignition capacitor C3 and the ignition switch S1 are connected in series with the freewheeling diode D2 connected in parallel to the primary coil L1, which forms a primary circuit. The anode of the freewheeling diode and one terminal of the ignition capacitor C3 are connected to ...
