Abstract :
The recently proposed modular multilevel converter “Hexverter” offers many advantages in high-voltage and high-power applications. This paper presents an improved Hexverter topology by introducing magnetically coupled branch inductors. These lead to a simplified system behaviour and a reduced amount of material for the branch inductors.
