Abstract
A fault current limiter may include a current limiting leg to transmit a first current and a control leg in parallel with the current limiting leg, the control leg to transmit a second current. The control leg may include a plurality of power electronic modules arranged in electrical series with one another, and a bypass power electronic module arranged in electrical series with the plurality of power electronic modules. The control leg may further include a plurality of current monitors arranged electrically in series with the plurality of power electronic modules and the bypass power electronic module, and at least one triggering circuit, wherein the plurality of current monitors is electrically coupled to the at least one triggering circuit, and wherein the at least one triggering circuit is coupled to at least one of: the plurality of power electronic modules, and the bypass power electronic module.
