Abstract
A method is described for activating a multiphase machine that has a link circuit equipped with a link circuit capacitor, phase windings, and one high-side switch and one low-side switch per phase. The switches associated with the individual phases have control signals applied to them by a control unit. The control unit provides, in successive activation cycles, pulse-shaped control signals for the switches, the pulse widths and pulse onsets of which are respectively varied within an activation cycle in such a way that the link circuit current is reduced.
