Zusammenfassung:	System and method for controlling a three-phase inverter as a non-linear current source, the inverter being connected to a three-phase network or load. The system comprises: means for measuring the voltage Ucc in the DC area of the inverter;means for measuring the components (ua, ub, uc) of the voltage of the load; means for measuring the components (ia, ib, ic) of the current of the load; and control means. The control means are used to obtain the spatial phasor Ug (ua, uß) of the measured voltage; to obtain the spatial phasor ig (ia, iß) of the measured current; to obtain the increase in current ?ig = ig ?-ig, i ? (i?, i?ß) being the reference spatial current; to calculate the voltage spatial phasor U conv (Uc a, Uc ß) to be applied so that the current ig progresses towards ig ?; and to apply the switching times of the transistors of the inverter by modulating spatial phasors.
