Summary: | A method of controlling voltage balancing of a modular multi-level converter is provided. The method includes receiving state information on each of n sub modules in an arm module, grouping the n sub modules into m sub module groups, receiving first state information on each of sub modules in a first one of the m sub module groups, among the state information on each of the n sum modules, receiving second state information on each of sub modules not included in the first sub module group, among state information on each of the n sum modules previously stored in a memory, controlling switching of a sub module by using the first state information and the second state information, and updating the memory with the first state information. |
