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.

Abstract: A drive and motor system and method for a six phase machine with negligible common-mode voltage is provided. The six-phase machine includes six phase windings divided into at least two windings groups configured to generate a zero common-mode pulse width modulation. The drive and motor system and method can also include at least one direct current source and a six phase inverter switching between positive and negative power of the at least one direct current source.
