Abstract
Control method for an electronic DC/AC converter (), wherein for at least one phase: calculating a first reference voltage (e, e, e) from predefined voltage setpoints () and a phase voltage (V, V, V); calculating a second reference voltage based on a difference between a predefined upper current limit (I) and the current (i, i, i) of said at least one phase, and on the phase voltage; calculating a third reference voltage based on a difference between a predefined lower current limit (−I) and the current of said at least one phase, and on the phase voltage; comparing the first reference voltage (e, e, e) with the second reference voltage selecting the lowest voltage of the two; comparing the selected reference voltage with the third reference voltage selecting as the control voltage (e, e, e) the highest of the two; and applying the selected control voltage (e, e, e) to the at least one phase of the converter.
