Abstract

Abstract Translated from German Gegenstand der Erfindung ist eine Wechselrichterschaltung, an die ein Induktionsmotor (1) angeschlossen ist, der eine Arbeitsmaschine antreibt. Es wird die Leistungsnahme aus dem Wechselstromnetz auf einen für den jeweiligen Lastfall minimalen Wert geregelt. Weiterhin wird die Frequenz der Wechselrichter­schaltung der Last der Arbeitsmaschine derart angepaßt, daß eine von der Drehzahl der Arbeitsmaschine abhängige physika­lische Größe gleich bleibt. The invention relates to an inverter circuit to which an induction motor (1) is connected which drives a work machine. The power consumption from the AC network is regulated to a minimum value for the respective load case. Furthermore, the frequency of the inverter circuit is adapted to the load of the work machine in such a way that a physical variable which is dependent on the speed of the work machine remains the same.
