Space vector PWM technique for a three-level asymmetrical six-phase drive

Abstract

Abstract−A space vector pulse-width modulation (SVPWM) strategy for a three-level asymmetrical six-phase drive, with a single neutral point, based on vector space decomposition (VSD) approach is presented for the first time in this paper. The selection process, related to the determination of the right switching sequences for the proposed modulation strategy, is discussed in detail. The developed SVPWM strategy is then simulated in PLECS simulation package, while driving an asymmetrical six-phase induction machine running at no load. Obtained results prove the validity of the algorithm.

Multiphase Traction Inverters: State-of-the-Art Review and Future Trends

“…With the trend in the automotive industry to upgrade powertrains from 400 V to 800 V and beyond [7], [127], MLI is expected to compete with the dominant 2L VSI, let alone supersede it. Multiphase MLIs (MPMLIs) have been studies in [128]- [132]. Five-, six-and seven-phase 3L neutral-point-clamped (NPC) inverters were investigated in [131], [129], [132] and [133], respectively.…”
