For transformerless current‐fed medium voltage drives, low‐order harmonics of common‐mode voltages (CMVs) are more concerned with than peak values. To mitigate low‐order harmonics, the average values of CMVs should be suppressed.

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.

A new modulation method for multilevel converters [PDF]
This paper presents a simple method for modulation in multilevel converters, which is hardly affected with the number of levels. The method is based on a simple graph, whose x-axis is directly related to the extra degree of freedom associated with ...

Space vector modulation technique for 3-level NPC converter with constant switching frequency [PDF]
This paper presents a simple Space Vector Modulation (SVM) methodology for a three-level NPC converter. Nearest three vectors (NTV) and corresponding duty cycles are deduced through simple generic mathematical expressions. Extra degrees of freedom of NPC
