Abstract
A circuit arrangement () for controlling a stator winding () of a stator () of an electric machine () is provided. The stator winding () has at least four electrical phases (φ), which are designed to be supplied with a separate phase current (I), respectively. A modulation signal (M) is assigned to each electrical phase (φ) and the modulation signals (M) are out of phase with respect to one another so that the stator winding () is designed to generate a rotary field. At least two carrier signals (T) are provided for generating the phase currents (I), and the electrical phases (φ) are divided into at least two groups, each of which is assigned a carrier signal (T). The carrier signals (T) have a phase shift (θ) relative to one another. Furthermore, an electric machine () comprising a circuit arrangement () is provided.
