Abstract :
Multiphase drives are particularly attractive in medium and high-power applications such as railway and naval propulsion systems. In the most modern drives, a multiphase machine is driven by an IGBT inverter. This paper focuses the theoretical calculation of the power losses in multiphase inverters with an odd number of phases. This analysis could be useful for a preliminary assessment of the drive efficiency, and allows to compare inverters with a different number of phases.
