IGCT Based Solid State Resonant Conversion

, 2020
Driven by the environmental changes, penetration of renewables and the need for more flexible power grid, DC is reemerging as a basis for future power networks. Already established in the area of HVDC for very long distance transmission, more and more attention is drawn to DC for distribution purposes, especially MVDC collection grids for offshore wind

Recent Advances in Design of Fault Current Limiters for Modern Power Grid Networks: A Critical Review

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
Fault current limiters (FCLs) are essential components in modern power systems for critical protection against the damaging effects of fault currents. With extensive short circuits, routine electrical faults, and an increasing risk of failure due to unprecedented events, the development of different types of FCL has gained attention.

New Bi-Mode Gate-Commutated Thyristor Design Concept for High-Current Controllability and Low ON-State Voltage Drop [PDF]

, 2016
© 2016 IEEE. A new design approach for bi-mode gatecommutated thyristors (BGCTs) is proposed for high-current controllability and low ON-state voltage drop. Using a complex multi-cell mixed-mode simulation model which can capture the maximum controllable

Towards next generation power grid transformer for renewables: Technology review

Engineering Reports, Volume 6, Issue 4, April 2024.
This paper develops a technical framework for the next‐generation power grid transformer (NGPGT) for grid renewables to address the environmental challenges produced by the explosive use of nonrenewable power generation sources. The use of these sources cannot meet the required electricity for the world's growing community due to their availability ...

Holographic studies of Einsteinian cubic gravity

, 2018
Einsteinian cubic gravity provides a holographic toy model of a nonsupersymmetric CFT in three dimensions, analogous to the one defined by Quasi-topological gravity in four. The theory admits explicit non-hairy AdS$_4$ black holes and allows for numerous

Controlled transition full-bridge hybrid multilevel converter with chain-links of full-bridge cells [PDF]

, 2016
This paper proposes a controlled transition full-bridge (CTFB) hybrid multilevel converter (HMC) for medium and high voltage applications. It employs a full-bridge cell chain-link (FB-CL) between the two legs in each phase to generate multilevel bipolar ...
