Abstract
An apparatus for breaking a line bidirectional current and a control method therefore. The apparatus comprises a breaking current branch circuit and an on-state current branch circuit, the breaking current branch circuit comprises one nonlinear resistor being connected in parallel to one first power semiconductor device, or one nonlinear resistor being connected in parallel to at least two first power semiconductor devices mutually connected in series; and the on-state current branch circuit comprises at least one bidirectional power semiconductor switch being connected in series to at least one high-speed isolation switch. The apparatus also comprises a bridge-type branch circuit. An apparatus for breaking a line bidirectional current, thereby greatly reducing costs of the apparatus and reducing difficulty in device layout, mounting and wiring of the apparatus on the premise of ensuring a breaking speed that is quick enough and a low loss.
