Title (EN) DRIVE CIRCUIT FOR DRIVING A GAS-DISCHARGE DEVICE
(FR) CIRCUIT DE COMMANDE POUR UN DISPOSITIF A DECHARGE DE GAZ
Abstract: front page image
(EN)A circuit for driving a gas-discharge device wherein discharge cells (120) each have a column electrode (28) and a segment electrode (26), includes a transformer (80) whose secondary winding (86) provides operating voltages for application to the electrodes. In operation, the secondary winding (86) is arranged during first time intervals to supply to the column electrodes (28) a first potential while a reference potential is applied to the segment electrodes (26). During second time intervals, the secondary winding (86) is arranged to supply to selected segment electrodes (26) a second potential, the reference potential being applied to selected column electrodes (28). Cells including selected column and segment electrodes are repeatedly ignited. A voltage regulator circuit (196) is coupled to the secondary winding (86).
(FR)Un circuit pour commander un dispositif de decharge de gaz dans lequel des cellules de decharge (120) possedent chacune d'elles une electrode de colonne (28) et un electrode de segment (26), comprend un transformateur (80) dont l'enroulement secondaire (86) fournit des tensions de fonctionnement d'application aux electrodes. En fonctionnement, l'enroulement secondaire (86) fournit pendant des premiers intervalles de temps aux electrodes de colonne (28) un premier potentiel tandis qu'un potentiel de reference est applique aux electrodes de segment (26). Pendant des seconds intervalles de temps, l'enroulement secondaire (86) fournit a des electrodes de segment selectionnees (26) un second potentiel, le potentiel de reference etant applique a des electrodes de colonne selectionnees (28). Des cellules comprenant des electrodes de colonne et de segment selectionnees sont allumes de maniere repetee. Un circuit regulateur de tension (196) est couple a l'enroulement secondaire (86).
