Abstract

CIRCUITO DE CONVERSION DE UNA TENSION ALTERNA EN UNA TENSION VARIABLE. EL CIRCUITO SE ALIMENTA A TRAVES DE UN TRANSFORMADOR (TL), UNO DE CUYOS BORNES (4) SE CONECTA A LA CARGA (1) A TRAVES DE UN FILTRO CO,PUESTO POR UNA BOBINA (LS) Y UN CONDENSADOR (CF), CONECTANDOSE EL OTRO BORNE (5) A UN INTERRUPTOR (I) DRE ESTADO SOLIDO CONTROLADO POR UNA SEÑAL OBTENIDA DE LA INTEGRACION DE LA TENSION DE ENTRADA AL INTERRUPTOR (I) Y POSTERIOR COMPARACION CON UNA TENSION DE REFERENCIA (VREFE), CON LO QUE SE OBTIENE EN LA CARGA UNA TENSION (VS) PROPORCIONAL AL VALOR MEDIO DE LA TENSION DE ENTRADA. APLICACION A BOBINAS DE BARRIDO VERTICAL DE TELEVISION.
