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
