ABB Semiconductors’ phase control thyristor has been the back-bone of the high power electronics industry since its introduction 60 years ago. Its field of application ranges from kW DC-drives and MW rated load commutated frequency converters to GW converters for HVDC transmission.
Due to the growing demand for energy efficiency, the thyristor remains at the heart of much of the equipment needed for energy transmission and distribution, as it allows the best performance in terms of cost, reliability and efficiency.
ABB was the first company to introduce 6” thyristor products for HVDC applications and ABB offers the most complete range of high power thyristors. New thyristor products continue to be developed with focus on minimizing overall losses and maximizing the power rating of the device.
ABB’s PCT product range includes presspack devices with ratings of 1,600 V – 8,500 V and 350 A – 6,100 A used in demanding applications such as HVDC, FACTS and DC-drives. These components have set benchmark reliability records over many years.
