Abstract
A power converter for coupling an electrical machine to an electrical grid includes a machine side converter and a grid side converter, each, side having a plurality of corresponding stages for converting a three-phase electrical signal of the electrical machine to a three-phase electrical signal of the electrical grid. The machine side converter includes a plurality of single-phase bridges coupled in series. The grid side converter includes a plurality of three-phase bridges. Each three-phase bridge corresponds to one of the single-phase bridges of the machine side converter. Each three-phase bridge is coupled to the primary windings of a corresponding transformer. The secondary windings of each corresponding transformer is phase-shifted from its primary windings and is coupled to secondary windings of another respective transformer, thus providing for coupling of the three-phase bridges in a series.
