Phase control thyristors
Phase control thyristor has been the backbone of the high-power electronics industry since its introduction almost 50 years ago and has set benchmark reliability records over many years.
The field of PCT applications ranges from kW drives and MW rated line commutated frequency converters to GW converters for HVDC trans- mission.
Hitachi ABB Power Grids offers the most complete range of high-power thyristors, including 6“ devices. New products continue to be developed with focus on minimizing overall losses and maximizing power ratings.
Applications using two antiparallel thyristors
can take advantage of Hitachi ABB Power Grids’ innovative bi-directionally controlled thyristors (BCTs) that incorporate two antiparallel thyristors in a single housing (see page 44).
