Abstract (en)

[origin: WO2016128194A1] In an active converter (102) which is connected to an electrical machine (101), in which clamping circuits for activating voltage clamping after a first time are provided, and which is also set up to activate a load shedding reaction only if activation conditions are present after a second time, the activation conditions comprise the fact that it is determined that a voltage potential applied to the supply side of an excitation winding of the electrical machine (101) at the second time is between the voltage potential applied to the first DC voltage connection (B+) and an earth potential if the excitation winding is disconnected from the voltage potential of the vehicle electrical system voltage and/or a current flowing through the excitation winding is below a current threshold value and/or, after a load shedding reaction has been activated for the first time, after which further load shedding reactions have been activated, more than one predefined period has elapsed and/or more than a predefined number of load shedding reactions have been activated.
