Abstract

A method controls a three-phase converter with a voltage intermediate circuit by pulse-width modulation for supplying a polyphase system, in particular a three-phase machine. The converter is operated with at least two different modulation methods which are selected from among the group of modulation methods which includes single-phase switching, two-phase switching and three-phase switching, and for changeovers to be made between the at least two different modulation methods depending on the operating state of the polyphase system.
