Control method for an electronic DC/AC converter (1), wherein for at least one phase: calculating a first reference voltage (er,v, es,v, et,v) from predefined voltage setpoints (22) and a phase voltage (Vcr, Vcs, Vct); calculating a second reference voltage ( e r , i pos , e s , i pos , e t , i pos ) based on a difference between a predefined upper current limit (Imax) and the current (ir, is, it) of said at least one phase, and on the phase voltage; calculating a third reference voltage ( e r , i neg , e s , i neg , e t , i neg ) based on a difference between a predefined lower current limit (−Imax) and the current of said at least one phase, and on the phase voltage; comparing the first reference voltage (er,v, es,v, et,v) with the second reference voltage ( e r , i pos , e s , i pos , e t , i pos ) selecting the lowest voltage of the two; comparing the selected reference voltage with the third reference voltage ( e r , i neg , e s , i neg , e t , i neg ) selecting as the control voltage (er,s, es,s, et,s) the highest of the two; and applying the selected control voltage (er,s, es,s, et,s) to the at least one phase of the converter.
A control method for an electronic DC/AC three-phase converter (1), characterised in that the method comprises, for each phase of the conversion stage (11, 11′) of the electronic DC/AC converter (1):
