Abstract
A circuit arrangement for supplying a lamp wattage on a high-pressure gas discharge lamp in the form of an alternating current having an operating frequency, said operating frequency being frequency-modulated within large limits such that no acoustic resonances are embodied in the lamp. Amplitude modulation through the frequency response of an interface is compensated by modulating an amplitude of a supply voltage.
