Branch circuit protection for DC systems
2011 IEEE Electric Ship Technologies Symposium, 2011We present a new approach for protecting DC power distribution circuits against faults and negative incremental impedance instabilities. Like a circuit breaker, the device is passive until a fault occurs. Unlike a circuit breaker, the device operates in current limiting mode or in impedance transformation mode, according to the system requirements, and

DC Protection on the Electric Ship
2007 IEEE Electric Ship Technologies Symposium, 2007The need for DC power at continuous uninterrupted rates is a reality for ship survival during highly intense combat and regular travel. One of the new proposed distribution systems on the all-electric ship (E-ship) is designed using a DC distribution method (zones) in which the use of transformers and possible frequency issues/manipulations can be ...

Topologically Protected DC–DC Converters.pdf
This research paper explores the design and analysis of topologically protected DC–DC converters, integrating concepts from topological physics to enhance power conversion performance. Conventional power converters often suffer from noise susceptibility, component variations, and limited stability under transient conditions. By leveraging a topologicalopenaire +1 more source
DC GRIDS: New over current protection
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016Fuses and Circuit Breakers play an important safety role in electrical transportation systems. Challenging new applications, especially in DC grids, 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.

Converter-based DC Distribution System Protection
2018 IEEE Industry Applications Society Annual Meeting (IAS), 2018Dc distribution systems are being widely adopted in many industrial, commercial and military energy systems such as commercial buildings, data centers, off-shore wind farms, and shipboard power systems. A dc distribution system can improve energy efficiency and reduce the size or weight of power systems.

Overcurrent protection in pulse-width controlled DC-to-DC converters
1976 IEEE Power Electronics Specialists Conference, 1976A current-limiting circuit for use in pulse width controlled dc-to-dc converters is described. This circuit ensures reliable converter operation by providing device protection against various transient overcurrent stresses as well as against output overload conditions.
