Abstract

Many modulation techniques have been developed along the years to provide in medium and high-voltage converters a high power quality and minimum switching frequency. This paper introduces some popular modulation techniques for multilevel converters, whose major challenges are obtain the previous two features. The modulation strategies that are presented are specially focused in the three-phase three-level Neutral-Point-Clamped convert (NPC), which is one of the most used topology in industry and in renewable applications.
