Abstract
A double winding electric machine assembly including a double winding electric machine having a first stator winding and a second stator winding; a first converter including a first modulator and a first power unit whose output is electrically connected to the first stator winding; a second converter including a second modulator and a second power unit whose output is electrically connected to the second stator winding. The assembly includes a current determining system adapted to determine at least one instantaneous phase current in the output of the first power unit; and a synchronizing system adapted to analyse ripple in the at least one instantaneous phase current, and to synchronize the first modulator with the second modulator by adjusting a phase shift between the first modulator and the second modulator until a minimum peak-to-peak current is obtained.
