Abstract (en)

[origin: WO2016012301A1] The invention relates to a method (100) for controlling an at least generator-operable multi-phase electric machine (1), the phase connections (U-Y) of which are connected in an active bridge rectifier (2) respectively to a first DC current voltage connection (B-) via controllable first current valves (UL-YL) which can be switched on and off and to a second DC voltage connection (B+) via second current valves (UH-YH), wherein the method comprises, switching on the first current valves (UL-YL) in a generator operation of the electric machine (1) if an output voltage between the first DC voltage connection (B-) and the second direct voltage connection (B+) has exceeded an upper threshold value at an exceedance time, and switching off the first current valves (UL-YL) again only after the output voltage has run under a lower threshold value at an underrun time. The first current valves (UL-YL) are then each switched off again individually after the underrun time only if each indication value characterising a current flow in the phase connection (U-Y) associated with each current valve has a predefined property. The present invention also relates to means for implementing a corresponding method.
