Titolo: Stacked multilevel inverter topologies for variable speed drives applications

Abstract— Many interesting multilevel topologies have been reported for drive applications.
However, still the most popular topology is the NPC three level, especially for medium voltage drives applications. This shows that the industry is still looking for some viable alternative to this, with reduced power circuit complexity and with increased reliability for medium voltage drives applications. This lecture will focus on some of the recent work from my lab on five-level, nine level and forty nine level inverter topologies with reduced DC link voltages for variable speed drive applications. Elimination of the common point voltage fluctuations due to stacking
of cells, with a normal six phase IM drive will also be discussed .
