Different types of fault current limiters (FCLs) have been developed and designed based on non-superconducting DC reactors (NSDRs). This paper proposes a controllable dual-bridge FCL (CDBFCL) the NSDR for use in an AC-type micro-grid. It includes two series shunt bridge circuits. The is diode semiconductor switches coupled with line via transformer. thyristor parallel line. provides variable vo...
