A method is disclosed for controlling an electrical converter system with at least two electrical converters. The method comprises determining a pulse pattern for each electrical converter from a reference voltage of the respective converter. The method further comprises determining a sum current reference and at least one difference current reference, along with determining a measured sum current and at least one measured difference current. The method further comprises determining a sum current error and at least one difference current error, and determining a sum flux modification by multiplying a gain to the sum current error and at least one difference flux modification by multiplying a gain to the respective difference current error. The method additionally comprises mapping the sum and difference flux modifications to a converter flux modification for each electrical converter; modifying the pulse pattern for each electrical converter, and applying the modified pulse patterns to the converters.
