“…Nevertheless, in high power applications, inherent voltage scalability and design modularity are resulting in reevaluation of the competitiveness of some well established technologies, such as Line Commutated Inverters (LCIs) and VSCs. In addition to HVDC, other applications where MMCs are being considered or envisioned, are FACTS [2], grid interties [3], STATCOMs [4], MV drives [5], DC electric ships [6], etc. Motivation for the work presented in this paper comes from an increased interest in emerging concepts of Medium Voltage DC (MVDC) distribution grids [7], and lack of suitable conversion technology (preferably with galvanic isolation).…”
