Abstract

Vorgeschlagen wird eine Erkennung des Ausfalls einer Phase in einem - von mehreren Phasen einer Netzspannung N gespeisten - System mit Zwischenkreis 5 und Gleichrichter 4, wobei eine über den Gleichrichter 4 gleichgerichtete Gleichspannung uz (t) des Zwischenkreises 5 mit einem Vielfachen der Frequenz als Grundwelle pulsiert. Ein Messglied 10 stellt ein Fühlersignal u1 als Abbild der pulsierenden Gleichspannung uz (t) bereit. Der vorgeschlagen Erfindung liegt dabei das Problem zugrunde, Phasenausfall einer Phase zu erkennen und dabei die Abhängigkeit von der Versorgungsspannung aufzuheben. Dazu wird das Fühlersignal u1 einem Frequenzfilter 11 zugeführt, der ein Ausgangssignal u2 erzeugt, bei dem ein Signal mit einer Frequenz des Vielfachen der Netzfrequenz stark gedämpft ist, aber ein Signal mit einer Frequenz unterhalb der Hälfte dieses Vielfachen der Netzfrequenz deutlich weniger gedämpft ist. Das Ausgangssignal u2 wird einer Schaltung 12 zugeführt, mit einer Erkennung des Ausfalls einer der Phasen.
