Abstract

A control device () for an inverter () that feeds an electric machine (), wherein the control device () is configured to provide pulse-width-modulated switching signals () at a carrier frequency to drive switching elements () of the inverter (), wherein the control device () is configured to ascertain the carrier frequency within at least one operating range () depending on a piece of operating point information that describes an operating point defined by a rotation speed and a torque of the electric machine () in such a way that the carrier frequency is reduced within the at least one operating range () compared to a maximum carrier frequency operating point at which a maximum carrier frequency is specified in the operating range.
