Abstract
FUENTE DE ALIMENTACION CONMUTADA, EN ESPECIAL PARA RECEPTOR DE TELEVISION EN COLOR. EL DISPOSITIVO INTERRUPTOR DE LA FUENTE DE ALIMENTACIPON CONMUTADA COMPRENDE UN TRANSISTOR MOS Q2, QUE ACTUA COMO ELEMENTO DE CONMUTACION, UN AMPLIFICADOR OPERACIONAL IC2, QUE GOBIERNA AL TRANSISTOR MOS A TRAVES DE UN TRANSISTOR AMPLIFICADOR Q1, Y UNA PLURALIDAD DE RESISTENCIAS R11, R12, R13 Y R21 CONECTADAS A LA ENTRADA NEGATIVA DEL AMPLIFICADOR OPERACIONAL IC2 CONECTADAS A LA ENTRADA NEGATIVA DEL AMPLIFICADOR OPERACIONAL IC2 DE MANERA QUE LA TENSION APLICADA EN DICHA ENTRADA ESTE RELACIONADA CON LA TENSION CONTINUA DE GOBIERNO Y CON LA TENSION DE UN ARROLLAMIENTO AUXILIAR L2 DE REFERENCIA. TAMBIEN COMPRENDE UN AMPLIFICADOR OPERACIONAL IC1 CONECTADO A LAENTRADA POSITIVA DELAMPLIFICADOR OPERACIONAL IC2, UNA RESISTENCIA R20 DISPUESTAENTRE EL POLO NEGATIVO DE LA TENSION CONTINUA DE ENTRADA Y LA TENSION NEGATIVA O MASA DEL CIRCUITO DE REFERENCIA, UNA RESISTENCIA R4 CONECTADA ENTRE LA RESISTENCIA R20 Y LA ENTRADA POSITIVA DEL CIRCUITO OPERACIONAL IC1, Y UN DIODO ZENER DZ1 CONECTADO TAMBIEN A LA ENTRADA POSITIVA DEL AMPLIFICADOR OPERACIONAL IC1. SE CONSIGUE UNA TENSION INDEPENDIENTE DE LAS VARIACIONES DE LA TENSION DE RED.
