A method for operating an electric machine with a power source and with an electric motor and with an intermediary power converter, wherein an input current of the power source is converted into a multi-phase output current for the electric motor by means of a pulse width modulated control of a plurality of semiconductor switches of the converter, wherein during each period of control, for at least one phase, a pulse with a pulse duration is generated during a period duration, wherein in a period, a pulse is divided into a leading first half-pulse and a trailing second half-pulse with in each case half a pulse duration, and wherein the first half-pulse with a first displacement time and the second half-pulse with a second displacement time are mutually shifted in time within the period duration of the period.
