Abstract

UNA UNIDAD DE PANTALLA DE VIDEO INCLUYE UNA FUENTE DE ALIMENTACION INCORPORADA Y EN MODO CONMUTADO (SMPS 5) Y MEDIOS DE CONTROL (7), QUE RESPONDEN A LA PRESENCIA DE UNA O MAS SEÑALES ACTIVAS DE SINCRONIZACION (HSYNC, VSYNC) PARA ENCENDER LA UNIDAD DE PANTALLA A PARTIR DEL MODO DPMS OFF, EN EL QUE CONSUME UNA CANTIDAD MINIMA DE POTENCIA Y AL QUE SE CONMUTA EN AUSENCIA DE CUALQUIER SEÑAL ACTIVA DE SINCRONIZACION. UN CIRCUITO DE DETECCION DE PICO (30) EXTRAE POTENCIA DE LAS SEÑALES DE SINCRONIZACION PARA ACCIONAR UN OPTOACOPLADOR (32), PERO EL ACCIONAMIENTO SOLO SE PERMITE SI EL CIRCUITO DE DETECCION DE CA (31) DETECTA QUE SE ENCUENTRA ACTIVA AL MENOS UNA SEÑAL DE SINCRONIZACION CUANDO ESTA CERRADO EL CONMUTADOR (33). UN CONMUTADOR (22) DESCONECTA EL CONTROLADOR SMPS (23) DE LA FUENTE DE POTENCIA DE ARRANQUE (21) HASTA QUE ES ACCIONADO EL OPTOACOPLADOR.
