Abstract
Proposed is a submodule of an MMC converter configured to stably supply power to a submodule controller controlling the submodule of an MMC converter. The submodule includes: an energy storage part storing electric energy therein; a plurality of switching elements connected in parallel to the energy storage part to have a shape of a bridge; a plurality of serially-connected resistors connected in parallel to the energy storage part; a plurality of DC-DC converters connected in parallel to a resistor of the plurality of resistors; a power switching part operating to select and output one voltage of voltages output from the plurality of DC-DC converters and a plurality of voltages input from outside; and a submodule controller operating with the voltage output by the power switching part so as to control switching operations of the plurality of switching elements.
