Abstract
A method of controlling a frequency converter comprises steps for measuring phase currents flowing in a three-phase supply network, for generating a first modulation space vector that comprises an angle that is synchronous to a supply voltage of the three-phase supply network and a determined modulation index as an amplitude, for generating a third modulation space vector depending on the first modulation space vector and the measured phase currents and for modulating the frequency converter according to the third modulation space vector.
