Abstract
An apparatus for limiting a current of a line or breaking a current, and a control method thereof are disclosed. The apparatus includes a current breaking branch () and a bridge branch. The bridge branch includes two bridge arms formed by four identical current commutation branches. Every two of the four current commutation branches are connected in series, and the formed two bridge arms are then connected in parallel. The two bridge arms are both connected in parallel to the current breaking branch, and middle points of the two bridge arms are separately connected to two ends of a line. Each current commutation branch includes at least one high-speed isolation switch () and at least one bidirectional power semiconductor switch () that are connected in series. The apparatus can turn off currents in two directions.
