Known ignition systems have a capacitor charged by a voltage source and discharged via a switch. In the present invention the voltage source is connected across a first capacitor, and this is connected via a thyristor and a diode to a tapping of an inductance. The inductance is connected in series with one electrode of a second capacitor, the output to the igniter being connected across the other electrode of the second capacitor and the series connected inductance. The system has several charging circuits including the inductance, second capacitor and thyristor each connected to respective igniters, the thyristors being connected with a common triggering unit.
Les circuits d'allumage existants comportent un condensateur chargé par un générateur de tension et déchargé au moyen d'un rupteur. Selon la présente invention, le générateur de tension est connecté aux bornes d'un premier condensateur qui est raccordé à une prise d'un inducteur par l'intermédiaire d'un thyristor et d'une diode. L'inducteur est raccordé en série à une des électrodes d'un second condensateur, la sortie vers l'allumeur étant raccordée à la seconde électrode du second condensateur et à l'inducteur connecté en série. Le circuit compte plusieurs circuits de charge comprenant inducteur, second condensateur et thyristor connectés aux allumeurs respectifs, les thyristors étant raccordés à un déclencheur commun.
