Verification of an IGBT Fusing Switch for Over- current Protection of the SNS HVCM

Abstract

An IGBT based over-current protection system has been developed to detect faults and limit the damage caused by faults in high voltage converter modulators. During normal operation, an IGBT enables energy to be transferred from storage capacitors to a H-bridge. When a fault occurs, the over-current protection system detects the fault, limits the fault current and opens the IGBT to isolate the remaining stored energy from the fault. This paper presents an experimental verification of the over-current protection system under applicable conditions. Keywords-component; IGBT; modulator; high voltage; high current, protection, fuse
