Abstract: A flying capacitor converter comprising a protection circuit includes at least two cells, each having a capacitor having a first and second DC sides, a first switch connected to the first DC side and to a capacitor of a following cell or an output circuit, and a second switch connected to the second DC side and to the capacitor of the following cell or the output circuit. During a nominal non-fault operation of the flying capacitor converter, only one of the first and second switches is in a conducting state, and during a fault operation where the first switch has a short circuit failure and the second switch has a conducting state, the protection circuit is configured to keep the second switch switched-on.

Abstract: The present invention is concerned with a four-level voltage source converter topology including two intermediate converter branches connecting two intermediate voltage levels to a load terminal, and including 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.
