Turn-Off Delay Compensation of Series-Connected IGBTs for HVDC Applications

Autor: Javier Chivite-Zabalza, J.C. Nicholls, Konstantin Vershinin, Pablo Briff

Publikováno v: IEEE Transactions on Power Electronics. 35:11294-11298

This letter shows a computationally inexpensive delay compensation algorithm for series-connected insulated-gate bipolar transistors (IGBTs). The algorithm adjusts the relative turn- off delays among series-connected IGBTs based on the measured clamp

Balancing Algorithm for a Self-Powered High-Voltage Switch Using Series-Connected IGBTs for HVDC Applications

Autor: Colin Charnock Davidson, Javier Chivite-Zabalza, David Reginald Trainer, J.C. Nicholls

Publikováno v: IEEE Transactions on Power Electronics. 34:8481-8490

This paper presents a balancing algorithm for the so-called Director Switch, a controlled, reverse conducting, self-powered, high-voltage switch, using series-connected insulated gate bipolar transistors (IGBTs). This is a key component on two new vo

Seagrass wasting disease: Nitrate enrichment and exposure to a herbicide (Diuron) increases susceptibility of Zostera marina to infection

Autor: Z. Ziauddin, R.G. Hughes, J.C. Nicholls, Maria Potouroglou

Publikováno v: Marine pollution bulletin. 134

Seagrass meadows suffered large-scale declines in the past century. The 'wasting disease', pathognomonically associated with Labyrinthula zosterae, reduced populations of Zostera marina on both sides of the North Atlantic in, and since, the 1930s, co
