Discontinuous space vector pulse width modulation techniques for a five-phase quasi Z-source inverter

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
In this paper, discontinuous space vector pulse width modulation for a five-phase quasi Z-source inverter is presented. Two schemes are introduced for the continuous SVM of five-phase qZSI (SVQ1 & SVQ2) and two schemes of discontinuous SVM (DSVQ1 & DSVQ2) are proposed SVQ1 method is based on subtracting the shoot-through state interval from the zero ...
