Abstract
A control device (8) for an inverter (2) that feeds an electric machine (3), wherein the control device (8) is configured to provide pulse-width modulated switching signals (15) for driving switching elements (12) of the inverter (2), wherein the control device (8) is configured to determine a modulation type by means of which the pulse-width modulated switching signals (15) are generated depending on operating point information that describes an operating point defined by at least one operating parameter, and to use a first modulation type in at least one first operating region (21, 28, 30, 31) and a second modulation type in another operating region (32, 32a, 32b).
