Common-mode components comparison for different SVM schemes in three-phase four-legged converter

Currently, space vector modulation (SVM) schemes are employed widely in three-phase power converter control. The impacts of different two-dimensional SVM (2D SVM) schemes on THD, switching losses and output ripple for three-legged converters have been discussed in literature. In this paper, the impact of various 3D SVM schemes on the common mode component is investigated. Nine different 3D SVM schemes for four-legged three-phase converters were considered in this paper.
