Abstract
A power supply system for an automobile vehicle headlight discharge lamp, the system including a DC/DC converter with a capacitor at its output, a DC/AC converter powered by the voltage across said capacitor, and a module for generating a high-voltage breakdown pulse designed to be connected in series with said discharge lamp to the output of the DC/AC converter, wherein it further includes a module for heating the electrodes of the discharge lamp design to be connected in series with the discharge lamp and the high-voltage pulse generator module and adapted to deliver, after the high-voltage breakdown pulse, a decreasing voltage which, at the terminals of said discharge lamp, is added to the voltage across the capacitor at the output of the DC/DC converter.
