“… High blocking voltage;  High continuous current capability;  Low on-state voltage drop ;  Low conduction loss;  High switching speed and low loss;  Suitable control technique and thermal management; Many power semiconductor devices have been developed for the HCLID applications such as; the insulated gate bipolar transistors (IGBT), SCR, gate turn-off (GTO) thyristor, emitter turn-off thyristors (ETO), and integrated gate-commutated thyristors (IGCT) [9]- [10]. These devices offer some improved characteristics compared with earlier conventional silicon devices For high power applications, traditionally, a high power SCR is used in [9] as the symmetrical power semiconductor device for a FCL. The operation of the SCR in a solid state FCL has advantages over others in multioperation capability, lower voltage drop, lower cost and higher reliability.…”

This paper describes the development of the hybrid fault current limiter and interrupting device (HCLID) which can be used successfully as a fast short-circuit protection means for low voltage AC industrial installations. The main components of the HCLID are a solid state commutation circuit that can supply a counter current injection from a stand-by pre-charged capacitor, saturable core reactor as the limiting impedance and fast mechanical contact switch all connected in parallel. Through this study, we can present a significantly improved and simplified approach that replaces the half-controllable silicon-controlled rectifier (SCR) in the commutation circuit with self-turn-off device such as integrated gate-commutated thyristor (IGCT). The use of highperformance semiconductors (IGCTs) as the commutating affords reduced recovery voltage, reduced losses, improved reliability and dynamic performance, and fast switching time (in μs). The new approach involves a fault detection using rate of current rise rather than the current magnitude and a time delay operating characteristic based on Piecewise Linear Electrical Circuit Simulation (PLECS) program. The control method is very simple. Simulations carried out during the research. Simulation results proved the practicability and validity of the new HCLID.

This research paper represents the estimation and reduction of eddy current loss in a Magnetic Fault Current Limiter (MFCL). The nonlinear model of the device is established using electromagnetic coupled circuit supported by Finite Element Model. The current limiting performance of the MFCL is investigated by simulation study as well as laboratory testing. It is further observed that a significant amount of eddy current loss takes place inside the core and permanent magnet of the device. Different methods (shorting ring, lamination of permanent magnet and variation of magnet length) are proposed to reduce the eddy current. The advantages and disadvantages of these methods are discussed. Some design modifications are also proposed to minimize the temperature rise caused by the eddy current.
