摘要
A method for acquiring values indicative of an AC current generable by an inverting stage of an inverter. The method includes at least a first line and a second line for providing a path for AC current between the inverting stage and the output stage. A current sensor is operatively associated to the first and second lines 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. The method may also include driving the inverting stage in such a way that the AC current in the first line has a first high-frequency ripple during a first-half of the current period, and in such a way that the AC current in the second line has a second high-frequency ripple during a second-half of the current period.
