Abstract
UN MODULADOR DE IMPULSOS ELECTRICOS MEJORADO. LA OSCILACION DEL CIRCUITO SE LOGRA CARGANDO ELEMENTOS DE ALMACENAMIENTO DE ENERGIA, TALES COMO UN CAPACITOR, Y DESCARGANDO EL CAPACITOR CADA VEZ QUE OCURRE UNA RELACION PREDETERMINADA ENTRE LAS CANTIDADES DE ENTRADA PRIMERA Y SEGUNDA. EL ENCLAVAMIENTO O FALLA DE OSCILACION, SE LOGRA DEBIDO A LA FALLA DE DESCARGA DEL CAPACITOR, CUANDO OCURRE UNA RELACION PREDETERMINADA POR MEDIO DE ELEMENTOS DE SUPERVISION, LOS CUALES PROPORCIONAN UNA SEÑAL DE DESCARGA AUXILIAR PARA DESCARGAR EL CAPACITOR CUANDO OCURRE UNA RELACION PREDETERMINADA POR MEDIO DE ELEMENTOS DE SUPERVISION, LOS CUALES PROPORCIONAN UNA SEÑAL DE DESCARGA AUXILIAR PARA DESCARGAR EL CAPACITOR CUANDO OCURRE LA RELACION PREDETERMINADA ENTRE LAS CANTIDADES DE ENTRADA.
