摘要： Provided is a modular multi-level converter (MMC) including a plurality of sub-modules including switching elements, and a central control unit which assigns an address to each of the plurality of sub-modules for distinguishing each of the plurality of sub-modules, determines switching operation conditions of the plurality of sub-modules based on the assigned addresses, and outputs switching signals corresponding to the determined switching operation conditions. The central control unit determines a switching sequence of the plurality of the sub-modules according to the sequence of the assigned addresses.

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.
