A novel over-current protection for digital power amplifier
2012 IEEE 11th International Conference on Solid-State and Integrated Circuit Technology, 2012The paper presents a novel over current protection circuit in digital power amplifier. The over current protection circuit would be used to shut down the output buffer when two output pins short-circuit to power supply, short-circuit to ground or short-circuit to each other.

Tuned Fuzzy Controller Based Over Current Protection Scheme
2008 Joint International Conference on Power System Technology and IEEE Power India Conference, 2008The measurands from the remote location are gathered at central control room (CCR) for processing, taking corrective action and presenting to higher hierarchy in a presentable format and it requires remote terminal unit to communicate between them. The pre-processing of current has been done using fuzzy logic algorithm for pre-processing the measurands

New over current protection technology addressing DC Transportation
2016 IEEE Transportation Electrification Conference and Expo (ITEC), 2016Fuses and Circuit Breakers play an important safety role in electrical transportation systems. Challenging new applications, especially in DC, have brought conventional current limiting devices to their limits. Indeed, mechanical circuit breakers may be too slow to open for networks with large DC fault currents. On the other hand, fuses may be too slow

Adaptive over current protection for distribution feeders with distributed generators
IEEE PES Power Systems Conference and Exposition, 2004., 2005The connection of distributed generators (DG) to distribution networks influences the performance of the networks. This paper focuses on the impact of DG on the feeder protection, specifically the impact on the overcurrent (OC) relay performance. The paper presents simulation results to show the extent of deterioration a DG can cause on the OC relay ...

A Review on Issues and Coordination Strategies for Over Current Protection in Microgrid
2017 14th IEEE India Council International Conference (INDICON), 2017This paper presents a review on issues and coordination strategies for overcurrent protection in microgrid. Microgrid has become more attractive because of its ability to deliver highly efficient, reliable and economic power to the customers. Also, Microgrid has a flexibility to operate in both grid connected and islanded modes of operation.

Fast, configurable over-current protection for high-power modules
2015 IEEE Electric Ship Technologies Symposium (ESTS), 2015Protection from over-current situations and the resulting risk of device failure is a requirement when testing limited-run, experimental modules. This paper demonstrates a fast, configurable, and consistent means for protecting against over-current conditions during Clamped Inductive Load (CIL) testing of 10 kV SiC MOSFET modules.
