2. Key Features
Asymmetric High-voltage Design
Specially designed for 4.5 kV medium and high-voltage systems. The asymmetric structure optimizes turn-off performance, requiring no additional RC snubber, simplifying topology and reducing cost and loss.
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.
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.
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 cost.
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 high-power drives such as rolling mills, fans, pumps and marine propulsion.
- Generator excitation systems: AC 800PEC excitation controller, realizing 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
Matching Drive
Must be used with ABB original drive board (common type: 3BHB003230R0101), powered by 24V DC with fiber control to ensure matching drive and protection logic and avoid device damage.
Cooling Solution
Adopt forced air cooling or liquid cooling, strictly control case temperature within -25℃~+70℃ to ensure long-term stable operation.
Series Application
Optimize dynamic voltage balancing by module turn-off consistency; du/dt snubber can be reduced or eliminated to improve system efficiency.
Installation Specification
Press-fit with specified torque to ensure uniform double-sided cooling and avoid mechanical stress and poor contact; proper grounding and insulation are required for high-voltage environments.
