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.

Figure 00000001
An electronic operating device for discharge lamps is disclosed, in which an output terminal is supplied to a reference potential (E) via a coupling capacitor (CB). To reduce the potential of an output terminal, an electrical component (VC) is inserted in series with the coupling capacitor (CB), which acts as a voltage source. In one embodiment, the electrical component (VC) consists of an inductance, which is coupled to the lamp inductor.
