Technical Specifications Rated Blocking Voltage: 4500V Rated Operating Current: 750A Gate Signal Interface: Fiber‑optic Switching Capability: Snubberless Operating Junction Temperature: -40℃ to +125℃ Storage Temperature: -40℃ to +85℃ Package Structure: Press‑pack double‑sided cooling Matching Hardware: ABB dedicated gate drive unit
Functional Features Supports high‑voltage large‑current switching action for power conversion circuit. Provides microsecond‑level fast forced turn‑off characteristic. Delivers low on‑state voltage drop to lower power consumption. Implements optical fiber isolated gate control to eliminate interference from high‑voltage main circuit. Supports multi‑device series connection for high‑voltage converter topology.
Application Scenarios
HVDC converter stations and FACTS devices such as SVC and STATCOM. Medium-voltage drives for metallurgical rolling mills, mine hoists, and large compressors. Ultra-high-capacity industrial power systems requiring high reliability and long service life.
Installation and Usage Notes
Install using a calibrated press applying the specified clamping force against a flat, clean heat sink. Connect the fiber-optic trigger and feedback cables to the TGU observing correct polarity. Verify the gate driver auxiliary supply is within tolerance before de-inhibiting the converter. Perform protective function tests (overcurrent, arc detection) before full-load operation. Do not handle the bare press-pack without proper mechanical protection.
