Switching technique comparison for five-phase voltage source inverter / Mohd Firdaus Ismail

This report presents the comparison between three switching techniques for a five-phase voltage source inverter (VSI) using Space Vector Modulation (SVPWM) approach. Three different techniques which are based on large vectors, the combination of large and medium vectors, and the combination of large...

Three different techniques which are based on large vectors, the combination of large and medium vectors, and the combination of large, medium, and zero vectors have been examined under a two-level five-phase inverter.

It can also be observed that the switching technique using combination of large and medium vectors has rapidly reduced the harmonic contents produced by d3-q3 subspace especially the 3rd and 7th harmonics order. Further reduction in the low order harmonic contents and phase- to-neutral voltages closer to sinusoidal waveform can be observed by implementation of zero vectors in the switching scheme. 2013 Thesis https://ir.uitm.edu.my/id/eprint/93642/ https://ir.uitm.edu.my/id/eprint/93642/1/93642.PDF text en public degree Universiti Teknologi MARA (UiTM) Faculty of Electrical Engineering Wan Abdul Munim, Wan Noraishah
