Abstract

The invention relates to a circuit arrangement for operating a high-pressure discharge lamp, provided with switching means, inductive means and rectifying means together forming a Buck converter, connected to input terminals for connection to a supply source and output terminals for connection of the lamp, comprising means for supplying the lamp with a current through periodic switching of the switching means alternately into a conducting and a non-conducting state by means of a switch-on and switch-off signal, respectively, which inductive means comprise a primary and a secondary winding, the secondary winding forming part of an integration network for generating the switch-off signal. The circuit arrangement is in addition provided with detection means for detecting a current which flows through the rectifying means.
