Abstract

Die vorliegende Erfindung bezieht, sich auf ein elektronisches Vorschaltgerät mit einem Wandler und Lampenanschlüssen zum Betrieb einer Niederdruckentladungslampe. Das elektronische Vorschaltgerät ist so ausgelegt, dass die Lampenanschlüsse galvanisch von dem Wandler getrennt sind und das zeitlich gemittelte Potential an den Lampenanschlüssen über ein Definitionspotential bestimmt ist.
