摘要： The invention relates to a device and a method for switching currents in a stator winding (1) of a generator/electric motor combination, said stator winding (1) comprising at least one winding which can be short-circuited or switched in a highly-resistive manner by means of at least one device (T1, D1; T2, D2). Said at least one winding is connected to a capacitor (C), by which means the voltage peaks thereof can be reduced as a result of switching processes, and energy stored in the stator winding can be temporarily stored. At least one switchable decoupling element (2) is arranged between the winding and the capacitor (C). The energy to be temporarily stored can be branched off as a charging current to the capacitor by means of the decoupling element (2), as a result of the disconnection of the device in a non-working cycle, and the temporarily stored energy can be fed back into the stator winding (1) as a working current in the working cycle. The decoupling element (2) is temporally controlled during the feedback in such a way that the capacitor voltage UC does not fall below a set voltage value.
