A novel improved combined Dynamic Voltage Restorer (DVR) using Fault Current Limiter (FCL) structure
2007 International Conference on Electrical Machines and Systems (ICEMS), 2007The dynamic voltage restorer (DVR) as a means of series compensation for mitigating the effect of voltage sags has been established as a preferred approach for improving power quality at sensitive load locations. In this paper a novel structure for voltage sags mitigation and for power quality improvement are proposed.

The Current-Diverting FCL-A Practical Solution to Fault Current Limiting
IEEE Transactions on Power Apparatus and Systems, 1980This paper is intended to bring to the attention of the electric power industry a practical means for achieving the benefits of fault-current limitation. This proposed scheme circumvents fundamental problems which have thus far prevented the realization of adequate, reliable fault limiters at high power voltage and current ratings.

Single AC/DC fault current limiter for both side of hybrid AC/DC microgrid
International Journal of Electronics, 2022Increasing short-circuit fault currents is one of the critical challenges in microgrids (MGs). In this paper, a novel AC/DC fault current limiter (ADFCL) is proposed to limit short circuit current of both DC and AC sides in hybrid AC/DC MGs (ADMGs).

Fault Current Limitation by a Transformer Type FCL Based on the Second Generation HTS Wires
IEEE Transactions on Applied Superconductivity, 2011A transformer type superconducting fault current limiter (FCL) for electric power grids was developed utilizing a nonlinear resistor made of the second generation HTS wire. Using of the second generation HTS wire instead of the first one was found to reduce by an order the required amount of superconducting materials.

Topology Modeling and Design of a Novel Magnetic Coupling Fault Current Limiter for VSC DC Grids
IEEE transactions on power electronics, 2021In a voltage-source converter dc grid, a dc fault current limiter (FCL) is a key apparatus. When faults occur, it is supposed to effectively and immediately suppress transient short-circuit current to protect other equipment, e.g., converters ...

Analysis of DC Fault and Current-limiting Capability of FCLs for VSC-based DC Distribution System
2019 IEEE Power & Energy Society General Meeting (PESGM), 2019DC distribution system has received wide interests for the higher efficiency and greater operational flexibility. However, DC fault current increases rapidly, which may cause IGBTs in converters to be blocked for self-protection. Fault current limiters (FCLs) are effective to limit the fault current in DC system.
