Abstract

METODO DE PROTECCION DEL ELEMENTO CONMUTADOR DE TIRISTORES DE UN GENERADOR DE IMPULSOS. EL METODO COMPRENDE EL DISPARO DEL TIRISTOR DEL ELEMENTO DE CONMUTACION A CONDUCCION SI OCURRE UNA DESCARGA DISRUPTIVA EN LA CARGA DURANTE UN PERIODO DE DISMINUCION DEL IMPULSO. ESTO SE CONSIGUE PONIENDO EN MARCHA UN TEMPORIZADOR (4) SIEMPRE QUE SE INICIA UN IMPULSO, FUNCIONANDO EL TEMPORIZADOR EN TANTO DURA EL IMPULSO, Y DETECTANDO LA PENDIENTE DE LA TENSION A TRAVES DE LA CARGA EN FUNCION DEL TIEMPO Y DISPARANDO EL TIRISTOR A CONDUCCION CUANDO LA PENDIENTE DE LA FUNCION DE TENSION EXCEDE DE UN VALOR PREFIJADO EN UN INSTANTE EN QUE EL TEMPORIZADOR ESTA FUNCIONANDO.
