Abstract:
A power supply system for an automobile vehicle headlight discharge lamp, comprising a DC/DC converter with a first capacitor (C.sub.o) at its output, a DC/AC converter powered by a voltage across said capacitor (C.sub.o), a high-voltage pulse generator module for generating a high-voltage breakdown pulse connected in series with said discharge lamp to the output of the DC/AC converter, and an electrode-heating module for heating electrodes of the discharge lamp connected in series with the discharge lamp and the high-voltage pulse generator module and adapted to deliver a voltage which, at the terminals of said discharge lamp, is added to the voltage across the capacitor. (C.sub.o) at the output of the DC/DC converter, and which decreases after the high-voltage breakdown pulse.
