MODULAR MULTI-LEVEL CONVERTER

摘要

Provided is a modular multi-level converter including a plurality of sub-modules including switching elements, a plurality of sub-control units respectively controlling the plurality of switching elements included in the plurality of sub-modules, and a central control unit which determines switching operation conditions of the plurality of sub-modules, and transmits control signals corresponding to the determined switching operation conditions to the plurality of sub-control units. Each of the plurality of sub-control units acquires state information on the sub-module controlled thereby and transmits the acquired state information to the central control unit.
