3. Working Principle
Structural Features
Integrated with gate drive and asymmetric thyristor chips, it combines the high-voltage and high-current capabilities of thyristors with the gate turn-off characteristics similar to IGBTs. No external turn-off circuit is required, simplifying the design.
Operating Mechanism
- Turn-on: Applying a positive voltage to the gate enables fast turn-on of the device with a low on-state voltage drop, suitable for high-current transmission.
- Turn-off: Applying a reverse voltage to the gate achieves fast turn-off through gate commutation with a turn-off time of approximately 100μs, adapted to low-frequency and high-power conversion.
- Protection Functions: Built-in overcurrent, overvoltage and overheating protection, which cooperates with the drive circuit to realize fast fault response and status feedback.
4. Installation and Maintenance
Installation Requirements
- Heat Dissipation: Adopt forced air cooling or water cooling systems to ensure the junction temperature stays within the safe range.
- Mechanical Fixation: Adapt to industrial standard installation dimensions; the tightening torque shall comply with manual specifications to prevent loosening caused by vibration.
- Electrical Connection: The main circuit busbar shall be designed with low inductance, and shielded wires shall be used for gate control lines to reduce electromagnetic interference.
Maintenance Key Points
- Regularly inspect the heat dissipation system (fans, water pumps, radiators) and clean dust and scale to ensure heat dissipation efficiency.
- Monitor the on-state voltage drop, gate drive voltage and temperature; troubleshoot module or drive faults in a timely manner if abnormalities occur.
- Conduct insulation tests in accordance with ABB specifications to avoid short circuits caused by insulation aging or damage.
5. Application Scenarios
- Power Transmission: Converters for HVDC and VSC-HVDC, adapted to 3000A+ and 4500V ratings, improving transmission efficiency and system stability.
- Industrial Drives: Variable frequency speed regulation of high-voltage motors (e.g., mining, metallurgy, ship propulsion), meeting megawatt-level power requirements with high efficiency and energy saving.
- Power Quality: Static Synchronous Compensator (STATCOM), Active Power Filter (APF), which mitigate grid harmonics and reactive power to improve power supply quality.
- Others: High-voltage UPS, induction heating power supplies, high-power test platforms and other high-voltage and high-power equipment.
