Assignee: AUDI AG
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A motor vehicle, comprising:
a DC power source;
an inverter; and
a drive device including an electric machine electrically connected to the DC power source via the inverter, wherein the drive device, in operation, determines a duty cycle depending on a nominal value taking into account dead times of switches of the inverter, controls the inverter with pulse width modulation based on the duty cycle, wherein the duty cycle is greater than 0 and less than 1, wherein the drive device controls the inverter with a continuous pulse width modulation when the duty cycle is less than a threshold value, and wherein the drive device switches the pulse width modulation from the continuous pulse width modulation to a discontinuous pulse width modulation when the duty cycles exceeds the threshold value.
