Abstract
CIRCUITO EXCITADOR DE ENERGIA CONSTANTE PARA UN ELECTROIMAN DE UN MARTILLO DE IMPRESION, O DISPOSITIVO SIMILAR, DESTINADO A IMPRESORAS DE IMPACTO.COMPRENDE UNA BOBINA (11) CONECTABLE A UNA FUENTE DE ALIMENTACION (BV1) NO ESTABILIZADA DE TENSION DE EXCITACION POR MEDIOS DE CONMUTACION (10) ACTIVADOS POR UNA SEÑAL DE ACTIVACION DE DURACION FIJA QUE HACE QUE FLUYA CORRIENTE EN DICHA BOBINA. UN CIRCUITO ONDULADOR HACE OPERAR CICLICAMENTE LOS MEDIOS DE CONMUTACION ACTIVABLES A UN NIVEL PREAJUSTADO DE DICHA CORRIENTE DURANTE DICHO INTERVALO PARA ONDULAR DICHA CORRIENTE DE MODOQUE SE OBTENGA UNA CORRIENTE MEDIA DE PICO DURANTE AL MENOS UNA PARTE DEL PERIODO RESTANTE DE DICHO INTERVALO, LA CUAL CORRIENTE MEDIA PUEDE HACERSE VARIAR PARA COMPENSAR CAMBIOS EN LA TENSION DE EXCITACION DE LA FUENTE.
