@article { , title = {Hybrid HVDC circuit breaker with self-powered gate drives}, abstract = {The ever increasing electric power demand and the advent of renewable energy sources have revived the interest in high-voltage direct current (HVDC) multi-terminal networks. However, the absence of a suitable circuit breaker or fault tolerant VSC station topologies with the required characteristics (such as operating speed) have, until recently, been an obstacle in the development of large scale multi-terminal networks for HVDC. This paper presents a hybrid HVDC circuit breaker concept which is capable of meeting the requirements of HVDC networks. Simulation results are presented which are validated by experimental results taken from a 2.5kV, 700A rated laboratory prototype.}, doi = {10.1049/iet-pel.2015.0531}, eissn = {1755-4543}, issue = {2}, journal = {IET Power Electronics}, pages = {228-236}, publicationstatus = {Published}, publisher = {Institution of Engineering and Technology (IET)}, url = {https://nottingham-repository.worktribe.com/output/776527}, volume = {9}, keyword = {fault tolerance, drives, HVDC power transmission, circuit breakers}, year = {2016}, author = {Effah, Francis Boafo and Watson, Alan James and Ji, Chao and Amankwah, Emmanuel K. and Johnson, Christopher Mark and Davidson, Colin and Clare, Jon C.} }
