Galvanically isolated modular converter [PDF]
IET Power Electronics, 2016 Direct current (DC) electrical grids are already a reality in low voltage (LV) telecom distribution systems and point‐to‐point high voltage DC transmission. Medium voltage (MV) domain, despite its big potential, still suffers from a lack of suitable conversion and protection technologies. This study presents a bidirectional, galvanically isolated, high
