There is a current limiter (10) for selectively limiting a rate of change of current in a DC electrical network. The current limiter (10) comprises: a first electrical block including an inductive element (24); and a second electrical block including a bidirectional switch (26), the first electrical block being connected in parallel with the second electrical block between first and second terminals (12, 14), the first and second terminals (12, 14) being connectable to the DC electrical network, wherein the bidirectional switch (26) is switchable to a first mode to permit current flow through the second electrical block in a first current direction and at the same time inhibit current flow through the second electrical block in a second current direction, the first and second current directions being opposite to each other, and the bidirectional switch (26) is switchable to a second mode to permit current flow through the second electrical block in the second current direction and at the same time inhibit current flow through the second electrical block in the first current direction, and wherein the current limiter (10) further includes a controller (28) to control the switching of the bidirectional switch (26) to each of the modes. |
