Title
(EN) LAMP POWER CIRCUIT SENSING METHOD AND SYSTEM
(FR) PROCEDE ET SYSTEME DE SONDE DU CIRCUIT DE PUISSANCE D'UNE LAMPE
Abstract
(EN) A lamp power circuit sensing system includes a unidirectional stage (22) having a unidirectional current, a bidirectional stage (24) operably connected to the unidirectional stage (22), and a power sensor (32, 34) operably connected to monitor the unidirectional current and to generate an indicated lamp signal (33, 35). The lamp power circuit sensing system further includes a power regulation circuit (19) having a lamp output (17) providing bidirectional lamp voltage (42), and a lamp voltage sensing circuit (26) operably connected across the lamp output (17) to generate indicated lamp voltage (46) in response to the bidirectional lamp voltage (42).
(FR) Ce système de sonde de circuit de puissance de lampe comporte un étage unidirectionnel (22) à courant unidirectionnel, un étage bidirectionnel (24) branché sur l'étage unidirectionnel (22), et une sonde de puissance (32, 34) montée de façon à surveiller le courant unidirectionnel et à produire une consigne lampe (33, 35). Ce système comporte également un régulateur de puissance (19) dont la sortie lampe (17) fournit une tension lampe bidirectionnelle (42) et un circuit sonde de tension lampe (26) branché sur la sortie lampe (17) de façon à produire la consigne de tension lampe (46) en fonction de la tension lampe bidirectionnelle (42).
