Solid-State Fault Current Limiting for DC Distribution Protection

This paper discusses solid-state fault current limiting technologies. Both solid-state fault current limiters and converters can quickly limit DC fault currents and permit other protective devices to perform appropriate fault interruption and/or isolation. Different system protection strategies using solid-state fault current limiters and converters are presented and analyzed. The advantages and disadvantages of different methods are also discussed and compared.Center for Electromechanic
