Abstract

SISTEMA CONTROLADO DE GENERACION DE FORMAS DE ONDA EN CUBAS ELECTROLITICAS DE ALUMINIO. ESTA FORMADO POR UNA ETAPA DE POTENCIA CON TRANSISTORES (10) ALIMENTADA DESDE UNA FUENTE DE ALIMENTACION SIMETRICA (4) A CUYA ENTRADA SE CONECTA LA SALIDA DE UN OPERACIONAL (11) QUE REALIZA LA DIFERENCIA ENTRE LA SEÑAL CORRESPONDIENTE A LA FORMA DE ONDA DESEADA GENERADA EN EL GENERADOR (12) Y LA FORMA DE ONDA REAL EN LA CUBA, POR MEDIO DE UNA RED DE ATENUADORES PARA TENSION O INTENSIDAD (13). LOS POTENCIOMETROS PUEDEN ESTAR CONTROLADOS POR LOS TEMPORIZADORES (14) Y (15) Y LA SEÑAL REAL QUEDA REGISTRADA EN EL APARATO REGISTRADOR (16).
