2. Key Features
High Integration Design
Built-in GTO chip, anti-parallel diode, gate drive and TMR protection circuit, no RC snubber required, simplifying the system, reducing components and improving reliability.
Fiber isolation provides strong anti-interference capability, suitable for high-voltage and strong electromagnetic environments.
Fiber isolation provides strong anti-interference capability, suitable for high-voltage and strong electromagnetic environments.
Fast Turn-off and Series Voltage Balancing
Turn-off time ≤ 1 µs, device-to-device variation < 0.2 µs, with excellent dynamic voltage balancing in series connection. Uniform voltage distribution among series modules reduces overvoltage risk.
Low Loss and High Efficiency
On-state voltage drop ≈ 2.0 V, low switching loss, system efficiency > 98%, suitable for high-power continuous operation.
High Reliability and Hardware Fault Tolerance
TMR (Triple Modular Redundancy) realizes microsecond-level fault response; short-circuit withstand 10 kA, turn-off within 3 µs; press-pack package features double-sided cooling, vibration resistance and long service life.
3. Typical Applications
- ABB ACS5000/ACS6000 medium-voltage inverters (690V–4.16kV)
- Generator excitation systems (e.g. AC 800PEC excitation controller)
- Medium-voltage high-power drives: rolling mills, fans, pumps, marine propulsion
- Flexible AC Transmission Systems (FACTS), SVG/STATCOM
- Wind/PV converters, energy storage converters
4. Matching and Selection Guidelines
- Matching drive: Original drive board (common type 3BHB018104R0001), powered by 24V DC with fiber control to ensure matched drive and protection functions.
- Cooling solution: Forced air cooling or liquid cooling, strictly control case temperature within -25℃~+70℃ for long-term stable operation.
- Series application: Optimize dynamic voltage balancing by 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.
