Abstract

The invention relates to a control unit (2) for an electric machine (1). The control unit has a power output stage (10) and a processing unit (14) that is connected to the power output stage. The processing unit is designed to actuate the power output stage in order to supply power to the electric machine and in order to produce a magnetic rotary field. The power output stage has at least one semiconductor switch half-bridge comprising two semiconductor switches (30,32;34,36;38,40), particularly field-effect transistors, wherein the semiconductor switches each comprise a diode (31,33) connected in parallel with the semiconductor switch. The power output stage is designed to rectify a voltage produced in the generator mode of the machine. According to the invention, the control unit has a current sensor (12,13) connected to the diodes. The current sensor is designed to sense a current flowing through the diode, and to produce a current signal that represents the current, in the generator mode. The control unit is designed to turn on the semiconductor switch connected in parallel with the diode on the basis of the current signal.
