Title
(EN) HIGH VOLTAGE DISCHARGE LAMP LIGHTING APPARATUS
(FR) DISPOSITIF D'ECLAIRAGE A LAMPE A DECHARGE HAUTE TENSION
(JA) 高圧放電灯点灯装置
Abstract
(EN) A high voltage discharge lamp lighting apparatus, wherein a high voltage required to light a high voltage discharge lamp can be obtained with the size of the whole apparatus reduced. A rectifier circuit (6), which is disposed on the secondary side of a transformer having a primary winding (3), a secondary winding (4) and a core (5) to receive a secondary side voltage, has a forward function and a flyback function. A voltage-doubler circuit (7) adds an output voltage generated by the rectifier circuit (6) to the secondary side voltage. Inclusion of the rectifier circuit (6) and voltage-doubler circuit (7) can efficiently boost the secondary voltage. Additionally, an inverter circuit (8) and a booster circuit (9) are disposed in a stage following the voltage-doubler circuit (7).
(FR) L'invention concerne un dispositif d'éclairage à lampe à décharge haute tension, nécessitant une tension élevée pour le fonctionnement de la lampe à décharge considérée. Aux fins de l'invention, tout le dispositif peut être réalisé avec une taille réduite. Un circuit redresseur (6), placé sur le côté secondaire d'un transformateur ayant un premier enroulement (3) un second enroulement (4) et un noyau (5) pour la réception d'une tension sur le côté secondaire, comporte une fonction de sens direct et une fonction de sens indirect. Un circuit doubleur de tension (7) ajoute une tension de sortie produite par le circuit redresseur (6) à la tension du côté secondaire. L'insertion du circuit redresseur (6) et du circuit doubleur de tension (7) peut apporter une élévation efficace à la tension du côté secondaire. Par ailleurs, un circuit inverseur (8) et un circuit élévateur (9) sont placés au niveau d'un étage qui se trouve après le circuit doubleur de tension (7).
(JA)  装置全体を小型化しつつ、高圧放電灯を点灯するために必要な高電圧を得ることが可能な高圧放電灯点灯装置である。すなわち、トランス(1次側巻線3,2次側巻線4,コア5)の2次側に配設され、2次側電圧が入力されるフォワード機能およびフライバック機能を有する整流回路6と、フォワード機能およびフライバック機能を有する整流回路6により生成された出力電圧を、2次側電圧と加算する倍電圧回路7とを備えることにより、2次電圧を効率よく昇圧する。また、倍電圧回路7の後段にインバータ回路8および昇圧回路9を接続する。
