Abstract
UN VOLTAJE DE ENTRADA DE ALIMENTACION ES ACOPLADO MEDIANTE UN DEVANADO PRIMARIO DE UN TRANSFORMADOR DE RETORNO A UN COLECTOR DE UN TRANSISTOR DE INTERRUPCION INTERMITENTE QUE OPERA A UNA FRECUENCIA DADA. DURANTE PARTE DE CADA PERIODO, CUANDO EL TRANSISTOR DE INTERRUPCION INTERMITENTE ES CONDUCTIVO, UN SEGUNDO INTERRUPTOR APLICA UN CORTOCIRCUITO A TRAVES DE UN DEVANADO SECUNDARIO DEL TRANSFORMADOR EN UN INSTANTE CONTROLABLE QUE HACE QUE LA CORRIENTE EMISORA DEL TRANSISTOR DE INTERRUPCION INTERMITENTE AUMENTE DE FORMA SIGNIFICATIVA. CUANDO LA CORRIENTE EMISORA SOBREPASA UN NIVEL DE UMBRAL PREDETERMINADO, SE ACTIVA UN DISPOSITIVO. CONSECUENTEMENTE, SE PRODUCE UN IMPULSO QUE APAGA EL TRANSISTOR DE INTERRUPCION INTERMITENTE Y LO MANTIENE NO CONDUCTIVO DURANTE EL TIEMPO EN EL QUE SE PRODUCE EL IMPULSO. UN IMPULSO DE RETORNO PRODUCIDO EN UN DEVANAO DEL TRANSFORMADOR ES RECTIFICADO PARA PRODUCIR UN VOLTAJE DE SALIDA DE ALIMENTACION DE CORRIENTE CONTINUA. LA LONGITUD DEL INTERVALO, CUANDO EL TRANSISTOR DE INTERRUPCION INTERMITENTE ES CONDUCTIVO, ES CONTROLADA MEDIANTE EL SEGUNDO INTERRUPTOR, DE ACUERDO CON EL NIVEL DEL VOLTAJE DE SALIDA DE ALIMENTACION EN RETROALIMENTACION NEGATIVA PARA REGULAR EL VOLTAJE DE SALIDA DE ALIMENTACION.
