In recent years, DC grids have gained momentum due to the advantages they display over
their AC counterparts. For instance, high voltage DC grids have been established as the
most prominent solution in the underwater power transmission or interconnection of
asynchronous systems. Consequently, the success of high voltage DC grids is expected to
be replicated in the medium voltage domain. However, medium voltage DC grids have not
been standardized yet, leaving the space for various research topics. To realize a flexible …

… ▶ Power density increase w/ conversion & isolation at higher frequency ▶ Grid
applications / traction transformer w/ different optimization objectives ▶ MFT design /
isolation are the bottlenecks … ⇒ the final choice depends on the application requirements
/ acceptable compromises between complexity and performance … ▶ Choice and
motivations for the choice completely different for an HVDC design compared to MVDC! …
