Claim:
1. A method for acquiring values indicative of an AC current generable by an inverting stage of an inverter, said inverter comprising: an output stage adapted to be operatively connected to one or more AC grids or loads; at least a first line and a second line for providing a path for said AC current between said inverting stage and said output stage; a current sensor operatively associated to said first line and second line and configured in such a way to generate a signal as a function of the sum between the AC current flowing in the first line and the AC current flowing in the second line; said method comprising: a) driving said inverting stage for generating said AC current in such a way that said AC current (I b) generating, through said current sensor, said signal as a function of the sum between the AC current flowing in the first line and the AC current flowing in the second line; and c) sampling values of said generated signal during said first-half period and said second-half period.
