摘要：
The invention relates to a control device for a voltage transformer of an electrically operated vehicle, which voltage transformer feeds an n-phase electric machine, n > 1. The control device comprises an observer unit, which is designed to determine a present rotational speed of the electric machine and a present output current of the voltage transformer, a computing unit, which is coupled to the observer unit and which is designed to compute an instantaneous wheel speed of the wheels of the vehicle in dependence on the determined present rotational speed, and a slip control unit, which is coupled to the computing unit and which is designed to at least temporarily apply a current correction amount to the output current of the voltage transformer if the present change of the wheel speed of the wheels exceeds a first predetermined threshold value.
