Abstract

SE DESCRIBE UN CIRCUITO DE PROTECCION DE UN AMPLIFICADOR DE POTENCIA (1) QUE ESTA ADAPTADO, A TRAVES DE LA LIMITACION DE LA CORRIENTE MAXIMA DE SALIDA DEL AMPLIFICADOR DE POTENCIA (1) Y DE LA RECARGA RAPIDA DE UNOS CONDENSADORES DE COMPENSACION (C1, C2, C3) SITUADOS EN EL AMPLIFICADOR DE POTENCIA (1), PARA LIMITAR LA CANTIDAD Y DURACION DE LA DESCARGA DE POTENCIA EN EL AMPLIFICADOR DE POTENCIA (1) CUANDO OCURRE SOBREEXCITACION DEL AMPLIFICADOR DE POTENCIA (1).
