Collection: ABB IGCT/IGBT Series

ABB IGCT (Integrated Gate-Commutated Thyristor) and IGBT (Insulated Gate Bipolar Transistor) are two types of power semiconductor switches utilized in medium and high voltage applications. Both are fully controllable devices, meaning they can be switched on and off through a gate signal.

IGCT is a hybrid device that combines the high current handling capacity of a thyristor with the fast switching capability of an IGBT. It is commonly used in applications requiring high power and high voltage, such as medium voltage drives, static var compensators (SVCs), and high voltage direct current (HVDC) transmission systems.

IGBT, on the other hand, is a more mature technology and is more widely employed across various applications. IGBTs are typically smaller and faster than IGCTs but have a lower current handling capacity. They find application in scenarios where medium power and high switching speed are essential, including variable frequency drives (VFDs), renewable energy systems, and electric vehicles.

ABB provides a broad range of IGCT and IGBT modules and systems designed for various applications. ABB's IGCT/IGBT modules are recognized for their high reliability, efficiency, and performance.
