A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

open access: yesEnergy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Impact of carrier injections on the threshold voltage in p-GaN gate AlGaN/GaN power HEMTs

open access: yes, 2019
We investigated the threshold voltage (V TH) shift in p-GaN gate AlGaN/GaN power HEMTs under both forward and reverse gate bias conditions at different temperatures. With increasing forward gate bias, the V TH first positively shifted and then decreased.
