2. Key Features
1. 4.5 kV Asymmetric High-voltage Design
Specially designed for 4.5 kV medium and high-voltage systems. The asymmetric structure optimizes turn-off performance without additional RC snubber, simplifying the topology and reducing cost and losses.
2. Snubber-less Integrated Design
Built-in GTO chip, anti-parallel diode, gate drive and TMR (Triple Modular Redundancy) protection circuit. High integration reduces external components and improves system reliability.
3. Fast Turn-off and Series Voltage Balancing
Turn-off time ≤1 µs, device-to-device variation <0.2 µs, excellent dynamic voltage balancing in series. Uniform voltage distribution among series modules reduces overvoltage risk, suitable for 6–12 kV high-voltage series topologies.
4. Low Loss and High Efficiency
Low on-state voltage drop and low switching loss, system efficiency >98%, suitable for high-power continuous operation and reducing operation and maintenance costs.
5. High Reliability and Hardware Fault Tolerance
TMR provides microsecond-level fault response; press-pack package features double-sided cooling, vibration resistance and long service life, adapting to harsh scenarios such as metallurgy, mining, wind power and marine propulsion.
3. Typical Applications
- ABB medium and high-voltage inverters: ACS6000/ACS8000 series (2.3–4.16 kV), for rolling mills, fans, pumps, marine propulsion, mine hoists.
- Generator excitation systems: AC 800PEC excitation controller for fast voltage regulation and fault protection.
- Grid and new energy equipment: Flexible AC Transmission Systems (FACTS), SVG/STATCOM, wind/PV converters, energy storage converters.
- Industrial heavy-load applications: Main rolling mill drives, mine hoists, petrochemical compressor drives.
4. Matching and Selection Guidelines
1. Matching Drive
Must be used with ABB original drive board (3BHB003387R0101 / GVC703AE01), powered by 24V DC with fiber control to ensure matching drive and protection logic.
2. Cooling Solution
Adopt forced air cooling or liquid cooling, strictly control case temperature within -25℃ ~ +70℃ to ensure long-term stable operation.
3. Series Application
Optimize dynamic voltage balancing by module turn-off consistency; du/dt snubber can be reduced or eliminated to improve system efficiency.
