Abstract

Offenbart ist ein Elektronisches Betriebsgerät für Entladungslampen, bei dem eine Ausgangsklemme über einen Koppelkondensator (CB) einem Bezugspotenzial zugeführt (E) wird. Zur Reduktion des Potenzials einer Ausgangsklemme wird seriell zum Koppelkondensator (CB) ein elektrisches Bauelement (VC) eingefügt, das als Spannungsquelle wirkt. In einer Ausführungsform besteht das elektrische Bauelement (VC) aus einer Induktivität, die mit der Lampendrossel gekoppelt ist.
