Abstract

Vorgeschlagen wird eine Schaltung zum hochfrequenten Betrieb zumindest einer Lampe mit einem aktiven Oberwellenfilter mit zumindest einem kapazitiven Pumpzweig mit einem Pumpkondensator (C1; C2) zur Energierückführung zu einem Glättungskondensator (C4) von einem lampenseitigen Anschlußpunkt zwischen einschließlich einem Mittenabgriff des Gegentaktfrequenzgenerators und einer ersten Lampenelektrode, dadurch gekennzeichnet, daß zwischen einem Punkt zumindest eines Pumpzweiges, der von dem Mittenabgriff des Gegentaktfrequenzgenerators aus hinter dem Kondensator (C1; C2) des Pumpzweiges liegt, und einem der Außenabgriffe ein Trapezkondensator (CT1; CT2) vorgesehen ist und somit der oder die Pumpkondensatoren des oder der Pumpzweige die einzigen direkt kapazitiv belastend an dem Mittenabgriff des Gegentaktfrequenzgenerators angeschlossenen Kondensatoren sind und/oder kein der Lampe im Betriebszustand unmittelbar parallel geschalteter Resonanzkondensator (C6) zur Lampenzündung vorgesehen ist.
