Abstract
A method for control of an externally excited electric machine of a motor vehicle, wherein a current flow is generated and/or controlled in at least one exciter winding of the electric machine by way of a power module connected to the exciter winding, wherein a counter-voltage is generated by way of a de-excitation module, connected to the exciter winding and arranged separately from the power module and operated separately from the power module, which is applied to the exciter winding and at least partly compensates for the voltage currently being generated by way of the power module and applied to the exciter winding, so that a de-excitation of the exciter winding occurs.
