Method for controlling a load with a predominantly inductive character, whereby in order to feed a phase of the above-mentioned load (3), use is made of at least two switched output voltages, applied by one or several power electronic inverters (11, 12; 34, 35, 36), with a given switching, modulation or sampling period, characterised in that the waveforms of the output voltages concerned are different or have been shifted in time, and in that they are supplied to the load (3) via a differential-mode device (6), whereby during every complete above-mentioned period, at least one of the above-mentioned output voltages is maintained constant and thus is not switched.
