Abstract

CIRCUITO DE CONTROL DE FALLO DE ALIMENTACION PARA MICROCOMPUTADORAS. UN VCR U OTROS EQUIPOS CONTROLADOS POR MICROCOMPUTADORA PUEDEN SUFRIR UNA INTERRUPCION EN EL SUMINISTRO DE CA COMO RESULTADO DE MUCHAS CAUSAS COMO ENCHUFANDO O DESENCHUFANDO LA FUENTE DE CA CON LA UNIDAD CONECTADA, REBOTE DE LOS CONTACTOS DEL INTERRUPTOR DE CA, FALLO DE LA FUENTE DE CA POR CONEXION DE ALTAS CARGAS, RAYOS, ETC. BREVES DESCONEXIONES DEL CA NO DEBERIAN RESULTAR EN LA PERDIDA DE LOS AJUSTES DEL USUARIO O EN LA NECESIDAD DE QUE EL USUARIO TENGA QUE RESTAURAR EL SISTEMA DE CONTROL PARA RECUPERAR LA CONDICION DE FUNCIONAMIENTO. PARA CONSEGUIR UNA INDICACION TEMPRANA DE INTERRUPCION INMINENTE DE LA ALIMENTACION, SE VIGILA LA FUENTE DE CA (Q1) Y SE GENERA UNA SEÑAL DE CONTROL (STOP (PARA)), LA CUAL ORDENA AL SISTEMA DE MICROCOMPUTADORA SALVAR LOS PARAMETROS ACTUALES Y ASUMIR UN MODO DE BAJA DISIPACION DE ENERGIA. AL RESUMIR LA ALIMENTACION, SE GENERA UNA SEÑAL DE RESET (REPOSICION), LA CUAL PERMITE EL COMIENZO DE NUEVO DEL SISTEMA DE MICROCOMPUTADORA. SE DETECTAN INTERRUPCIONES EN EL CA TAN BREVES COMO DOS CICLOS, Y SE GENERAN SEÑALES DE STOP (PARA) Y RESET (REPOSICION).
