Abstract

Die Schaltungsanordnung zum Betreiben von Glimm-Leuchtstofflampen (GLL) an einem Netz beinhaltet einen Transformator (TR) mit Magnetkern, einen Primärstromkreis mit einer Primärwicklung, der mit dem Netz, sowie einen Sekundärstromkreis mit einer Sekundärwicklung, der mit der Glimm-Leuchtstofflampe verbunden ist. Der Magnetkern des Transformators (TR) weist mindestens drei Schenkel (I, II, III) sowie zwei Joche auf. Die Primärwicklung (Wa) ist auf einen ersten Schenkel (I), ein erster Wicklungsteil (Wb1) der Sekundärwicklung auf denselben ersten Schenkel (I) und ein zweiter Wicklungsteil (Wb2) der Sekundärwicklung auf einen zweiten Schenkel (II) gewickelt. Mindestens ein dritter Schenkel (III) ist frei von jeglichen Wicklungen.
