摘要： The present invention concerns a superconducting fault current limiter (1 ) comprising a rectifier bridge (2) made of active devices (3a, 3b, 3c, 3d) connected to a circuit that is to be protected, said rectifier bridge (2) comprising four branches connected by means of four nodes (4, 5, 6, 7), wherein a first node (4) and a second node(5), not adjacent to said first node (4), are connected to said circuit that is to be protected (12, 13), characterized in that it comprises a central branch (8) connected from the third node (6) to the fourth node (7) of said rectifier bridge (2), comprising or consisting of at least one circuit element comprising an inductive component, whose aim is to reduce the amplitude of the ripple of the current through said central branch (8), and a nonlinear superconducting resistive component, having: - a first operating condition, wherein the current through said central branch (8) does not exceed a given threshold value, so that said at least one circuit element, comprising a nonlinear superconducting resistive component, is in the superconducting state; and - a second operating condition, wherein the current through said central branch (8) exceeds a given threshold value, so that said at least one circuit part, comprising a nonlinear superconducting resistive component, is in the non-superconducting state, thus offering a resistive behavior.
