1. Product Background

The IGCT technology was originally developed by ABB as an evolution of GTO (Gate Turn‑Off Thyristor) in high‑voltage power electronics field. Conventional SCR (silicon‑controlled rectifier) can only be turned on by gate signal and cannot actively turn‑off; GTO thyristor needs bulky, lossy snubber circuits for turn‑off. ABB invented IGCT to solve these pain points: integrating gate commutating unit directly inside press‑pack package, achieving snubber‑less turn‑off capability, combining ultra‑high current‑handling capacity of thyristor and fast active turn‑off performance similar to IGBT.

ABB 5SHX1960L0004 IGCT Module

Model 5SHX1960L0004 is a mature high‑power asymmetric reverse‑conducting IGCT unit for medium‑voltage industrial power conversion. The 3BHL000390P0104 stands for the complete assembled unit: IGCT chip + integrated gate drive PCB assembly, optical fiber trigger interface, snubber capacitors and press‑pack water‑cooled mechanical housing, widely deployed in ABB medium‑voltage converter product lines.

Press‑pack (hockey‑puck) ceramic sealed package is adopted, designed for long‑term continuous heavy‑duty industrial service, thermal‑cycling resistance and cosmic‑radiation tolerance for power grid‑level equipment.

2. Core Functions

1. High‑power bidirectional power switching: Realizes controlled turn‑ON and active forced turn‑OFF for high‑voltage / high‑current power circuits via optical fiber gate trigger signals, no large‑size snubber circuit required.More products: plcva.com
2. AC‑DC & DC‑AC energy conversion: Works as power switching core inside converters and inverters; converts AC to DC or DC to adjustable‑frequency AC. Embedded anti‑parallel freewheeling diode handles reverse current flow.

1. Precise power regulation: Controls magnitude and phase of output power by adjusting trigger timing, supports medium‑frequency operation up to ~10 kHz, low conduction voltage drop reduces power loss under large‑current working conditions.More products: plcva.com
2. System‑level reliability support: Press‑pack package permits failure‑to‑short mode (safe short‑circuit failure mode for series‑connected stacks); integrated gate‑drive monitoring detects gate‑circuit abnormality for system protection interlock. Water‑cooled interface supports continuous full‑load operation.

Key typical electrical specs (datasheet baseline):

• Repetitive peak off‑state voltage: 6000 V
• Continuous on‑state RMS current: 1960 A (water‑cooled, 25 ℃)
• Non‑repetitive surge current: 6000 A /10 ms
• Control interface: Fiber‑optic optical trigger, high noise immunity
