Abstract
A current controller for controlling plural stator currents of plural stator windings of an electrical machine, in particular a generator, is provided, wherein the plural windings are separately connectable to a converter. The current controller includes a positive-sequence current controller configured to provide a first voltage command, in particular in a rotating dq+ frame, based on the plural stator currents; a negative-sequence current controller configured to provide a second voltage command, in particular in the dq+ frame, based on the plural stator currents. Further, the current controller includes a summation system for adding the first voltage command and the second voltage command to obtain a summed voltage command based on which the converter is controllable.
