Constant Common-Mode Voltage Strategies Using Sigma-Delta Modulators in Five-Phase VSI

This article proposes and studies different sigma-delta (\Sigma\Delta) modulation strategies for obtaining a constant common-mode voltage (CMV) by eliminating the CMV level transitions in a five-phase voltage source inverter (VSI). These techniques are based on choosing vectors that generate a const...
