ABB Thyristors

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.

Bi-directionally controlled thyristors (BCT)

SCR thyristors are typically used as phase-controlled current valves for AC to DC conversion and vice versa, operating at low frequencies (most often around AC line frequency). In the conducting state, thyristors feature very low losses, making them attractive devices to efficiently control very high currents and energies.

All ABB Thyristors are press-pack devices. They are pressed with a fairly high force onto heat-sinks which also serve as electrical contacts to the thyristor terminals.
