ABB 5SHY2645L0004 Reverse Conducting IGCT Module

Technical Specifications Internal Device: Integrated anti‑parallel freewheeling diode Package Type: Press‑pack double‑sided cooling Gate Control Interface: Fiber‑optic Switching Speed: Microsecond‑level Operating Junction Temperature: -40℃ to +140℃ Storage Temperature: -40℃ to +85℃ dv/dt Withstand Capability: High‑grade Cooling Mode: Forced‑water‑cooled or forced‑air‑cooled clamping installation

Functional Features Supports integrated freewheeling diode function to simplify power circuit topology. Provides fast snubberless turn‑on and turn‑off performance. Delivers low conduction loss to reduce overall system energy consumption. Implements optical fiber gate drive for full galvanic isolation between high‑voltage main circuit and low‑voltage control circuit. Supports series connection for higher‑voltage converter application.

Application Scenarios

Core switching component in ABB ACS series medium-voltage drives. Deployed in HVDC Light and FACTS systems. Suitable for voltage source inverters, current source inverters, and active front-end rectifiers in heavy industrial applications.

Installation and Usage Notes

Mount the module on a suitable heat sink observing the specified mounting force and torque values. Ensure proper cooling (forced-air or liquid) is provided and verified before energizing. Connect the gate drive interface with correct polarity and low-inductance wiring. Verify all protective functions are configured in the converter control system. Perform a controlled startup with gradual voltage ramp-up while monitoring leakage currents and gate driver feedback.
