Abstract

SE CONECTA A UN CONMUTADOR DE LA FUENTE DE ALIMENTACION DEL TRANSFORMADOR DE CIERRE QUE OSCILA LIBREMENTE CON UN ELEMENTO DE CONEXION SEMICONDUCTOR Y MANEJABLE (V11) DE UN DISPOSITIVO DE DIRECCION (IC) ASI COMO PARA UNA CONEXION RCP (R6, C5, V5) PARA UNA LIMITACION DE LA TENSION PUNTA DE LOS SOBREOSCILADORES EN UNA DESCONEXION DEL ELEMENTO DE CONEXION SEMICONDUCTOR (V11) UN PRIMER BORNE DE ENTRADA (2) DEL DISPOSITIVO DE DIRECCION (IC) PARA LA COLOCACION DE UNA SEÑAL DE REPRODUCCION DE CORRIENTE PRIMARIA EN EL PUNTO DE ENLACE DE UN ESLABON RC(R30, C4). ESTE ESLABON RC DEPENDE CON SU CAPACIDAD (4) DEL POTENCIAL DE SUMINISTRO Y CON SU RESISTENCIA (R30) DEL PUNTO DEL CONTACTO P1 DEL RECTIFICADOR DE DIRECCION UNICA (V5), DEL CONDENSADOR (C5) Y DE LA RESISTENCIA (R6) PERTENECIENTES A LA CONEXION RCD. VENTAJA: EN CUANTO FALLE LA RESISTENCIA (R6) EN LA CONEXION RCD(R6, C5, V5) Y RESULTE DE ELLO UNA LIMITACION DE LA TENSION PUNTA, EL DISPOSITIVO DE DIRECCION (IC) VUELVE A REGULAR AUTOMATICAMENTE LAREGULACION DE LA CONEXION DEL ELEMENTO DE CONEXION SEMICONDUCTOR (V11). ESTE (V11) ES ASI EFICAZMENTE PROTEGIDO CONTRA LA DESTRUCCION A CAUSA DE UN RECALENTAMIENTO.
