The invention relates to a method for operating a high-pressure discharge lamp using a bipolar supply current, which has a temporally cyclic waveform, and a predetermined electrical power, the high-pressure discharge lamp being supplied with an additional electrical power at cyclically repeating time intervals directly following the zero crossing of the supply current in order to stabilize the lamp operation, and the total power, averaged over time, corresponding to the predetermined electrical power.
