Abstract :
This paper presents a simple Space Vector Modulation (SVM) methodology for a three-level NPC converter. Nearest three vectors(NTV) and corresponding duty cycles are deduced through simple generic mathematical expressions. Extra degrees of freedom ofNPC converter are used to fully benefit from SVM advantages and to control the switching frequency. Simulation and experimentalresults are presented and discussed to validate the proposed methodology
