Реферат: CE DISPOSITIF COMPORTE UN TRANSFORMATEUR DONT L'ENROULEMENT SECONDAIRE EST DIVISE EN PLUSIEURS SECTIONS 5, 7, 9, 11 BRANCHEES EN SERIE A TRAVERS DES DIODES 13, 15, 17. L'EXTREMITE AVANT DE LA PREMIERE SECTION 5 EST RACCORDEE A UN POINT DE POTENTIEL CONSTANT A TRAVERS UNE AUTRE DIODE 31, ET EN OUTRE, L'EXTREMITE AVANT ET L'EXTREMITE ARRIERE DE LA PREMIERE SECTION SONT RACCORDEES AUDIT POINT A TRAVERS DES CONDENSATEURS. DE CE FAIT, LA VALEUR DE LA TENSION D'UNE LIGNE DE DERIVATION 23 BRANCHEE PAR EXEMPLE DEVANT LA DEUXIEME SECTION 7, EST AU CHOIX COMPRISE ENTRE LA DIFFERENCE DE TENSION ENTRE L'EXTREMITE AVANT ET L'EXTREMITE ARRIERE DE LADITE SECTION, ET LE DOUBLE DE CETTE DIFFERENCE DE TENSION. APPLICATION: AUX RECEPTEURS DE TELEVISION EN COULEUR. THIS DEVICE INCLUDES A TRANSFORMER WHOSE SECONDARY WINDING IS DIVIDED INTO SEVERAL SECTIONS 5, 7, 9, 11 CONNECTED IN SERIES THROUGH DIODES 13, 15, 17. THE FRONT END OF THE FIRST SECTION 5 IS CONNECTED TO A POINT OF CONSTANT POTENTIAL THROUGH ANOTHER DIODE 31, AND FURTHERMORE, THE FRONT END AND REAR END OF THE FIRST SECTION ARE CONNECTED TO THE AUDIT POINT THROUGH THE CAPACITORS. THEREFORE, THE TENSION VALUE OF A BYPASS LINE 23 CONNECTED FOR EXAMPLE IN FRONT OF THE SECOND SECTION 7, IS TO CHOOSE BETWEEN THE TENSION DIFFERENCE BETWEEN THE FRONT END AND THE REAR END OF THE SAID SECTION, AND THE DOUBLE THIS DIFFERENCE IN TENSION. APPLICATION: TO COLOR TELEVISION RECEIVERS.
