Abstract

L'INVENTION CONCERNE LES ALIMENTATIONS A DECOUPAGE REGULEES QUI PERMETTENT D'ALIMENTER SOUS UNE TENSION CONTINUE CONSTANTE UNE CHARGE VARIABLE TELLE QU'UN RECEPTEUR DE TELEVISION. ELLE CONSISTE DANS UNE ALIMENTATION CONNUE A GENERER LA TENSION DE POLARISATION DE LA GACHETTE DU THYRISTOR DE BLOCAGE A PARTIR DES IMPULSIONS DE TENSION PROVENANT DE LA CHARGE DU TRANSFORMATEUR LORSQUE LE TRANSISTOR HACHEUR EST SATURE, AU LIEU DE GENERER CETTE TENSION DE POLARISATION A PARTIR DES IMPULSIONS DE TENSION PROVENANT DE LA DECHARGE DU TRANSFORMATEUR LORSQUE LE TRANSISTOR HACHEUR EST BLOQUE. ELLE PERMET DE REALISER DES ALIMENTATIONS REGULEES QUI PEUVENT DEMARRER SUR UNE CHARGE NOMINALE SANS DISJONCTER AU DEMARRAGE.THE INVENTION CONCERNS REGULATED SWITCHING POWER SUPPLIES WHICH ALLOW TO POWER A VARIABLE LOAD, SUCH AS A TELEVISION RECEIVER, UNDER A CONSTANT CONTINUOUS VOLTAGE. IT CONSISTS OF A POWER SUPPLY KNOWN TO GENERATE THE POLARIZATION VOLTAGE OF THE LOCKING THYRISTOR TRIGGER FROM THE VOLTAGE PULSES ARISING FROM THE TRANSFORMER LOAD WHEN THE CHICKER TRANSISTOR IS SATURATED, INSTEAD OF GENERATING THIS VOLTAGE PULSES. OF VOLTAGE FROM UNLOADING THE TRANSFORMER WHEN THE CHOPPER TRANSISTOR IS BLOCKED. IT ALLOWS REGULATED POWER SUPPLIES THAT CAN START ON A NOMINAL LOAD WITHOUT BREAKING UP ON START-UP.
