Low　voltage　direct　current　(LVDC)　distribution　network　is　one　of　the　important　carriers　of　new　DC　sources　and　loads.　However,　the　voltage　source　converter　(VSC),　as　its　important　energy　conversion　device,　does　not　have　fault　ride-through　capability.　At　the　same　time,　traditional　DC　circuit　breakers　are　difficult　to　isolate　faults　before　VSC　is　blocked,　which　makes　LVDC　system　have　huge　potential　safety　hazards.　This　paper　proposes　a　fault　adaptive　current　limiter　(FACL)　for　LVDC　systems　to　address　these　issues,　offering　superior　current　limiting　performance　to　traditional　schemes.　At　the　same　time,　FACL　has　a　certain　voltage　clamping　ability,　so　VSC　has　a　certain　fault　ride-through　capability.　First,　the　paper　introduces　the　topology　and　working　principle　of　the　proposed　FACL.　This　topology　can　ensure　＇low　intervention＇during　normal　operation　and　＇effective　current　limiting＇during　faults.　Subsequently,　the　parameter　design　scheme　of　FACL　is　proposed.　Additionally,　the　proposed　scheme　is　verified　by　simulation.　Finally,　the　conclusion　of　this　study　is　given.　©　Published　under　licence　by　IOP　Publishing　Ltd.
