Parallel connection of Integrated Gate Commutated Thyristors and diodes
2008 IEEE Power Electronics Specialists Conference, 2008This paper describes the parallel connection of 4.5 kV integrated gate commutated thyristors (IGCTs) and diodes. The impact of varying device characteristics on the stationary current distribution of parallel connected semi-conductors is investigated. Possible solutions to improve the current sharing at steady state are presented.

Voltage sags mitigation with an integrated gate commutated thyristor based dynamic voltage restorer
8th International Conference on Harmonics and Quality of Power. Proceedings (Cat. No.98EX227), 2002Voltage sags mitigation in distribution networks plays an important role in the improvement of power supply quality. Dynamic voltage restorers (DVR), when installed between the supply and a critical load feeder, can compensate for voltage sags within 2-3 milliseconds.
