Product Name
ABB KUC755AE106 3BHB005243R0106 High-Voltage Thyristor Gate Driver Module (also referred to as ABB Industrial Power Semiconductor Driver Board, ABB IGCT/Thyristor Trigger Control Module)
2. Product Description
ABB KUC755AE106 3BHB005243R0106 is a high-reliability gate driver module developed by ABB, specifically engineered for triggering and controlling high-voltage, high-current thyristors (SCRs) and integrated gate-commutated thyristors (IGCTs) in industrial power electronic systems. As a core component of ABB’s power semiconductor drive portfolio, this module integrates isolated power supply, signal amplification, fault detection, and protection circuits, providing stable and precise trigger signals to ensure reliable turn-on/off operations of power semiconductors.
The module features a rugged industrial-grade design with enhanced electromagnetic interference (EMI) immunity and wide environmental adaptability, making it suitable for harsh operating conditions in medium-voltage inverters, static var compensators (SVC), high-voltage direct current (HVDC) transmission systems, and industrial motor drives. It supports multiple thyristor/IGCT configurations (single, series, or parallel) and is fully compatible with ABB’s 5SHY/5STP series thyristors and 5SXE series IGCTs. With built-in over-voltage, over-current, and thermal protection functions, it effectively safeguards power semiconductors and the entire power system from damage caused by electrical abnormalities. The compact design and standardized mounting enable easy integration into power electronic cabinets, while compatibility with standard industrial communication protocols allows for remote monitoring and parameter configuration. Widely used in metallurgy, petrochemicals, power generation, and rail transit industries, this module plays a critical role in ensuring efficient and reliable operation of high-power conversion systems.
