Space vectors sets of voltage multilevel inverter part 1. Classic two-levels, NPC and dci circuit topologies

Abstract

The goal of this paper (in two parts) is to show the methodology and describe in comparative manner the space vectors sets for all typical multilevel inverters topologies. Part 1 of this paper is focusing on: classic two- level inverter, neutral-point-clamped (NPC) inverter and diode-clamped inverter (DCI) topologies. The set of complex space vectors for particular multilevel inverter circuits have been presented in this paper. The general equation for the number of unrepeatable vectors has been also presented.
