Abstract
A method and a circuit system for operating an electric machine are presented. The method is carried out in particular in a starting phase, a current being limited using a controllable resistor, the controllable resistor being implemented by at least one semiconductor switch, which is controlled using a clocked signal, and the signal being set in such a way that in shutdown phases, the at least one semiconductor switch is not completely shut down.
