Offline-Based SVM Techniques to Reduce Common-Mode Voltage of Six-Phase Cascaded-CSI

In this paper, space vector modulation (SVM) techniques are developed to operate the six-phase current-source inverters (CSI) while reducing the common-mode voltage (CMV) content associated with the switching of semiconductors. The CMV issue is a severe issue of high-power electronics converters that causes damage to electric drives and shortens their life span. Since the null states are the main contributor to CMV in SVM schemes, an optimum …
