Abstract

Bei Schaltungsanordnungen zum Betrieb von Entladungslampen (Lp1, Lp2), die eine Ladungspumpe zur Reduzierung von Netzstromoberschwingungen enthalten, kommt es beim Start der Lampen zu einen Energieungleichgewicht. Damit dies nicht zur Zerstörung von Bauteilen führt, dennoch aber genügend Zündspannung an den Lampen (Lp1, Lp2) erzeugt wird, kontrolliert ein Schwellwertschalter (MOV, TH) die Frequenz eines in der Schaltungsanordnung enthaltenen Wechselrichters.
