Abstract
A circuit arrangement for starting and for operating high-pressure lamps makes an increased transfer voltage available to the discharge lamp. The increased transfer voltage is generated by voltage doubling across a rectifier unit by means of a charging capacitor (LK), separated into two individual capacitors (C,C,), the common midpoint (M) of the capacitors (C,C,) being connected to the two network inputs of the rectifier unit.
