Overview

The ABB IGCT (Integrated Gate‑Commutated Thyristor) module is engineered for heavy‑duty industrial environments where precise power control and long‑term durability are essential. It combines the robustness of a thyristor with the controllability of an IGBT, making it ideal for high‑voltage direct current (HVDC) transmission, large motor drives, and renewable energy integration. Moreover, its compact design reduces system complexity, while advanced cooling and packaging technology ensure stable operation under extreme electrical and thermal stress. In addition, the IGCT’s fast switching capability minimizes losses, thereby improving overall system efficiency.

Technical Data

Typical Applications

• High‑voltage direct current (HVDC) transmission: Provides efficient switching for long‑distance power transfer.

• Large industrial drives: Used in steel mills, paper plants, and mining operations requiring megawatt‑scale motors.

• Renewable energy systems: Supports wind and solar integration into grid infrastructure.
