The Modular multilevel converter has become an attractive option for dc/ac conversion in many
power system applications in particular for HVDC transmission, due to its parallel arrangement of
phase legs the MMC is known to be wye configured architecture. In this modular converter
application used then of conventional converter the delta configured MMC enable by series-stacking
phase legs is on alternative realization to wye configured MMC and has significantly different
characterized. MMC enable greater flexibility in converter voltage/current scaling for given set submoduleand may be applying option for dc/ac application requiring a power tap-off a high
voltage dc rail.
