Method for Determining at Least One Current Fed to an Electrical Machine by Means of a Feedback Signal, Drive System and Motor Vehicle

A method for determining at least one current fed to an electrical machine of a drive system includes predefining a carrier frequency of the at least one current fed to the electrical machine, detecting an electromechanical feedback signal dependent on the at least one current, at a link circuit capacitor of the drive system, identifying a signal component associated with the at least one current in the feedback signal on the basis of the predefined carrier frequency, and determining the at least one current fed to the electrical machine on the basis of the signal component.
