Abstract

Die Erfindung betrifft eine Schaltungsanordnung zum Betrieb mindestens einer Niederdruckentladungslampe (LP1, LP2) an einem Wechselrichter (Q1, Q2). Die Schaltungsanordnung weist ein vereinfachtes Oberwellenfilter zur Begrenzung des Oberwellengehaltes des Netzstroms auf. Bei dem bevorzugten Ausführungsbeispiel wird das Oberwellenfilter von dem Stützkondensator (C2), der Diode (D1), dem Trapezkondensator (C7) und dem Resonanzkondensator (C6) gebildet.
