Abstract

Es wird eine Schaltungsanordnung zum hochfrequenten Betrieb einer oder mehrerer parallel zueinander geschalteter Nieder­ druckentladungslampen angegeben. Die Schaltungsanordnung weist einen Netzgleichrichter mit nachgeschaltetem aktiven Oberschwingungsfilter, einen nachgeschalteten Glättungskon­ densator und einen jeder Niederdruckentladelampe zugeordneten Hochfrequenzgenerator auf. Der Hochfrequenzgenerator ist ein Eintakt-Hochfrequenzgenerator, der einen Schalttransistor (T1), eine Schaltinduktivität (L1) und einen Schwingungskon­ densator (C1) aufweist, und der, über zwei Dioden (D5, D6) vom Netz entkoppelt, an dem Glättungskondensator (C0) betrie­ ben ist.
