Fast-clamped short-circuit protection of IGBT's [PDF]
IEEE Transactions on Industry Applications, 1999 Identification of fault current during the operation of a power semiconductor switch and activation of suitable remedial actions are important for reliable operation of the power converter including the power semiconductor device. A short circuit is a basic and severe fault situation in a circuit structure such as a voltage source converter. This paper

Short-circuit protection for MV & LVDC grid [PDF]
2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014 A DC medium voltage (MV) and low voltage (LV) power distribution network will be proposed and the protection aspects will be discussed in this paper. This paper is mainly focused on the short-circuit overcurrent protection system of the future MV/LVDC distribution network. The proposed MV/LVDC distribution network would be modeled using PSCAD.
