ABSTRACT:
A method for controlling a frequency converter having multi-phase output is disclosed and a frequency converter for applying the method. In order to achieve a good waveform the currents of the frequency converter are controlled via modulation in such manner that the current modulation periods of each phase are interlaced with the modulation periods of the other phases.
