Reduction of output common mode voltage using a novel SVM implementation in matrix converters for improved motor lifetime (2014)
Journal Article

This paper presents the study of an alternative Space Vector Modulation (SVM) implementation for Matrix Converters (MC) which reduces the output Common Mode (CM) voltage. The strategy is based on replacing the MC zero vectors by the rotating ones. In...
