摘要： The present invention relates to a converter in which a plurality of sub-modules, each including an energy storage unit and power semiconductors, is connected in series to each other, wherein each of the sub-modules is configured by adding a simple and inexpensive auxiliary circuit unit between two half-bridge units, and thus fault current is allowed to flow into the energy storage unit of each half-bridge unit, thereby blocking or reducing the fault current. The present invention provides a converter including a plurality of sub-modules connected in series to each other, wherein each of the sub-modules includes a first half-bridge unit including a first energy storage unit, and a plurality of first power semiconductors connected in parallel to the first energy storage unit and connected in series to each other; a second half-bridge unit including a second energy storage unit, and a plurality of second power semiconductors connected in parallel to the second energy storage unit and connected in series to each other; and an auxiliary circuit unit connecting the first half-bridge unit and the second half-bridge unit; wherein the auxiliary circuit unit includes a single third power semiconductor and a single diode.
