Protection for distributed generations in the DC micro-grid
2011 2nd IEEE PES International Conference and Exhibition on Innovative Smart Grid Technologies, 2011In this paper, an analysis results for the protection of a DC micro-grid is described. The 400V DC micro-grid consists of a wind power system (Permanent Magnet Synchronous Generator, PMSG), a photo-voltaic system, a fuel cell system and energy storages. Abnormal operating conditions during various faults are studied. According to a series of studies, a

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
Implementation of control and protection logics for a bidirectional DC/DC converter
2010 IEEE International Symposium on Industrial Electronics, 2010In this paper, a control strategy for a bidirectional DC/DC power converter is discussed, and the logics to guarantee the operation correctness in various operative modes and for safety requirements are considered. In Buck (or step- down) mode, a voltage PI regulator is proposed, whereas in Boost (or step-up) mode an inner current control loop is ...

Protection of DC and hybrid AC-DC microgrids with ring configuration
2017 7th International Conference on Power Systems (ICPS), 2017This paper presents protection techniques for DC and hybrid AC-DC microgrids. The DC microgrid protection is proposed based on difference of transient energy at both ends of the line to be protected using voltage and current measurements. Method can identify the fault is either internal or external.

DC overcurrent protection-Where we stand
Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting, 1993The procedures used to determine the DC ratings for fuses and the issues pertinent to ensuring a proper DC fuse application are discussed. For a better understanding of how fuses are rated for DC, Underwriters Laboratories UL Standard 198L is examined.
