Wind energy conversion systems (WECS) are increasingly higher due to the great demand of wind energy. Thus, the power converter will play a more important role in the next generation of large WECS. Currently, the most accepted ac-ac power converter for WECS is the conventional twolevel back-to-back (2L-B2B). However, 2L-B2B is expected not to provide an acceptable performance for the largest of...
