Medium voltage direct current (MVDC) technology has been experiencing a great boom of interest in recent years. This paper aims at giving a contribution to this field by proposing a new converter topology for MVDC applications. This topology is characterized by a low number of sub-modules (SMs) which is strongly related to the converter footprint and complexity. The new topology sizing is compared to the modular multilevel converter (MMC) for the same requirements to highlight advantages and disadvantages of the proposed solution.
