(FR) CIRCUITS PILOTES POUR APPAREIL D'ÉCLAIRAGE À SEMI-CONDUCTEURS À INTENSITÉ RÉGLABLE
Abstract
(EN)
A voltage regulator for generating a housekeeping voltage in a high voltage power supply circuit includes a charging switch coupled to a high voltage node and to a storage device at an output node, and a control voltage regulation circuit coupled to the charging switch and configured to cause the charging switch to generate a current pulse for charging the storage device.
(FR)
Le régulateur de tension selon l'invention permettant de générer une tension domestique dans un circuit d'alimentation électrique à haute tension comprend un commutateur de charge couplé à un nœud à haute tension et à un dispositif accumulateur à un nœud de sortie, et un circuit de régulation de tension de commande couplé au commutateur de charge et configuré pour que le commutateur de charge génère une impulsion de courant pour charger le dispositif accumulateur.
