Abstract

Die Erfindung betrifft eine Schaltungsanordnung zum Betrieb elektrischer Lampen mit einem selbstschwingenden Halbbrückenwechselrichter (Q1, Q2). In die Steuerkreise der Halbbrückenwechselrichtertransistoren (Q1, Q2) ist jeweils ein Hilfstransistor (T1, T2) geschaltet, so daß der Emitterwiderstand jedes Halbbrückenwechselrichtertransistors (Q1, Q2) von einer Parallelschaltung gebildet wird, die aus mindestens einem ohmschen Widerstand (R5) bzw. (R7) und der parallel dazu angeordneten Steuerstrecke des entsprechenden Hilfstransistors (T1) bzw. (T2) besteht. Die Steuereingänge beider Hilfstransistoren (T1, T2) sind außerdem an den Ausgang einer gemeinsamen Steuerschaltung (IC) angeschlossen. Diese Maßnahmen ermöglichen es, den wirksamen Emitterwiderstand und damit die Rückkoppelung des Halbbrückenwechselrichters (Q1, Q2) in Abhängigkeit von den Betriebsphasen der Lampe (LP) umzuschalten und so auf einfache Weise die Taktfrequenz des Halbbrückenwechselrichters in weiten Grenzen durch die Dimensionierung der Widerstände (R5, R6; R7, R8) der erfindungsgemäßen Parallelschaltungen (R5, R6, T1) bzw. (R7, R8, T2) zu variieren.
