    Abstract: The present invention is concerned with a four-level voltage source converter topology having two intermediate converter branches connecting two intermediate voltage levels to a load terminal, and having a interconnect switch coupling the two intermediate branches. The interconnect switch replaces two controlled switches present in corresponding four-level prior art topologies. The four-level converter thus requires, for a full bidirectional implementation, only five active switches. The reduced number of active switches/gate drivers and the four available output voltage levels make this solution interesting for lower cost power electronics with improved reliability, good power quality and minimized filtering requirement.
