Abstract

CE BALLAST EST MUNI D'UN COMMUTATEUR SEMICONDUCTEUR 22 DE TYPE G.T.O. (GATE TURN-OFF SWITCH). SELON L'INVENTION, LE BALLAST SEMICONDUCTEUR EST MUNI D'UN TRANSFORMATEUR 23 ALORS QUE PAR L'INTERMEDIAIRE D'UN DEUXIEME ENROULEMENT 25 DE CE TRANSFORMATEUR, UNE IMPULSION DE COURANT PASSANT PAR UN PREMIER ENROULEMENT 24 DE CE TRANSFORMATEUR BRANCHE EN SERIE AVEC LA LAMPE, CONDUIT A UNE IMPULSION D'EXTINCTION POUR LE COMMUTATEUR 22 DE TYPE G.T.O. ON OBTIENT AINSI UN BALLAST SEMI-CONDUCTEUR QUI NE COMPORTE QUE PEU DE COMPOSANTS ELECTRIQUES. APPLICATION: ECLAIRAGE GENERAL.THIS BALLAST IS EQUIPPED WITH A G.T.O. TYPE 22 SEMICONDUCTOR SWITCH (GATE TURN-OFF SWITCH). ACCORDING TO THE INVENTION, THE SEMICONDUCTOR BALLAST IS EQUIPPED WITH A TRANSFORMER 23 WHILE THROUGH A SECOND WINDING 25 OF THIS TRANSFORMER, A CURRENT PULSE PASSING THROUGH A FIRST WINDING 24 OF THIS TRANSFORMER CONNECTED IN SERIES WITH THE LAMP , CONDUCTED TO AN EXTINGUISHING PULSE FOR THE GTO-TYPE SWITCH 22, A SEMI-CONDUCTIVE BALLAST IS THUS OBTAINED WHICH CONTAINS FEW ELECTRICAL COMPONENTS. APPLICATION: GENERAL LIGHTING.
