Abstract

Bei einem Verfahren zur Erzeugung einer getakteten Stellspannung (u) wird diese mit einer elektrischen Steuer­ größe pulsdauermoduliert. Die Stellspannung dient zur Beaufschlagung eines eine Induktivität aufweisenden Stel­ lantriebs, insbesondere eines elektromotorischen Stellan­ triebs (9) einer Drosselklappe (11) eines Verbrennungs­ motors. Um zugleich eine gute periodische Anregung des Stellantriebs sowie eine niedrige elektrische Verlustleistung in dem Stellantrieb zu erzielen, wird die mit einer hohen Takt­ frequenz (f₀) getaktete Stellspannung mit einer niedrigen Grundmodulationsfrequenz (fm) zusätzlich zu der Steuer­ größe pulsdauermoduliert. In a method for generating a clocked control voltage (u), this is pulse-duration modulated with an electrical control variable. The control voltage is used to act on an actuator having an inductor, in particular an electromotive actuator (9) of a throttle valve (11) of an internal combustion engine. In order to simultaneously achieve a good periodic excitation of the actuator and a low electrical power loss in the actuator, the actuating voltage clocked with a high clock frequency (f₀) is pulse-width modulated with a low basic modulation frequency (f m ) in addition to the control variable.
