Abstract
A method for estimating values assumed at a certain instant of each period by currents flowing respectively in two distinct windings of a poly-phase load controlled in a space vector modulation (SVM) mode, using a same measuring device, may include coupling the measuring device to the first winding and measuring a current flowing therethrough with an anticipation from the certain instant smaller than or equal to an SVM half-period. The method may also include coupling the measuring device to the second winding, measuring a current flowing therethrough at the certain instant, coupling the measuring device to the first winding, and measuring a current flowing therethrough with a delay equal to the anticipation. The method may also include estimating a value assumed at the certain instant by the current flowing through the first winding based upon the two measured values with the anticipation and with the delay respectively.
