Abstract
CIRCUITO DE SALIDA DE SEÑAL ALTERNA PARA PROPORCIONAR UNA SEÑAL DE SALIDA ALTERNA A UN CIRCUITO DE CARGA. CONSTA DE UN TRANSFORMADOR (1) CUYO DEVANADO SECUNDARIO (1A) SE CONECTA A LOS TERMINALES DE SALIDA (3); DE TERMINALES DE ENTRADA (2A, 2B) PARA RECIBIR LA SEÑAL DE ENTRADA, LOS CUALES ESTAN CONECTADOS A UNA SECCION DE FILTRO DE PASO ALTO, CAPACITIVA-INDUCTIVA, QUE COMPRENDE UN CAPACITOR (4, 5) Y UN TRANSFORMADOR (6, 7) EN SERIE; DE UN PUENTE RECTIFICADOR (8, 9) QUE RECIBE LA SALIDA DEL FILTRO; DE UN CAPACITOR DE CUATRO TERMINALES (10, 11) CONECTADO A LA SALIDA DEL PUENTE; Y DE DISPOSITIVOS ANTIPARALELOS AUTOCONMUTABLES. DE APLICACION EN SISTEMAS DE SEÑALIZACION DE FERROCARRILES.
