Comparison of superconducting fault current limiter topologies based on power electronic devices
Fault current limiter (FCL) technology regulates fault current along with capability to cut down voltage sag problems raised by faults in system. A superconductor fault current limiter (SFCL) technology has a high efficiency and compressed design. Silicon controlled rectifier (SCR) based technology limits the fault current during whole fault operation but it requires milliseconds of time to begin with fault protection. A fast response metal oxide semiconductor field effect transistor (MOSFET)/ insulated gate bipolar transistor (IGBT) based SFCL limits the fault current successfully. A thorough analysis and comparison of SFCL topologies on basis of switching elements has been presented in this paper. Simulation results shows that MOSFET based SFCL has fast response.
