Abstract

DC fault current limiters (FCLs) are of great significance to the safe and stable operation of DC distribution systems. Among the various FCLs, inductor-based FCLs play an important role. However, the issue of inductor saturation generally exists, which causes limitations in practical engineering applications. A novel LC-resonance-based FCL is proposed in this paper, which can suppress the inductor-saturation effect and create a natural zero-cross current for enhancing performance. In addition, it can cooperate with the AC circuit breaker (ACCB) to quickly cut off faults. A theoretical analysis and the parameter design of the proposed FCL are presented. Finally, a scaled-down experiment test platform is built, and experiment tests and simulation case studies are carried out to verify the working principle and superiorities of the proposed FCL.
