Abstract

Die Erfindung betrifft eine Überwachungsschaltung (ÜS) für ein Schaltnetzteil mit einer Gleichrichterschaltung (G) zum Gleichrichten einer primären Netzwechselspannung (AC). Die Überwachungsschaltung (ÜS) umfasst hierbei zwei Widerstandsteiler (W1, W2), umfassend jeweils zwei Widerstände (R1, R2, R3, R4). Die Widerstände (R1, R2, R3, R4) sind jeweils in Serie zwischen einer Phasenleitung (PH1, PH2) eines Netzanschlusses vor der Gleichrichterschaltung (G) und einem Bezugspunkt nach der Gleichrichterschaltung (G) angeschlossen. Die Überwachungsschaltung umfasst des Weiteren eine Subtraktionsvorrichtung (OP) mitzwei Eingängen,wobei jeder der zwei Eingänge der Subtraktionsvorrichtung (OP) jeweils zwischen den Widerständen (R1, R2, R3, R4) jeweils eines der Widerstandsteiler (W1, W2) angeschlossen ist. Die Erfindung betrifft des Weiteren die Verwendung einer Überwachungsschaltung.
