Abstract
A system and/or method for controlling a dual-three-phase machine with respect to a power electronics inverter is provided. The dual-three-phase machine includes six phase windings divided into at least two windings groups configured to provide a combination of six voltages that achieve zero common-mode voltage and a significantly reduced common-mode noise current.
