3. Working Principle
Structure and Mechanism
Structural Features: Integrated with gate drive interface and asymmetric thyristor chips, it combines the high-voltage and high-current capabilities of thyristors with the IGBT-style gate turn-off characteristics. No external turn-off circuit is required, which simplifies the design and improves reliability.
Operating Mechanism: Applying a positive voltage to the gate enables fast turn-on (with low on-state voltage drop, suitable for ultra-high current transmission); applying a reverse voltage achieves fast turn-off (approx. 100μs) through gate commutation, adapted to low-frequency and ultra-high-power conversion.
Protection Functions: Built-in overcurrent, overvoltage and overtemperature protection, which cooperates with the gate drive unit to realize fast fault response and status feedback, improving system safety.
4. Installation and Maintenance
Installation Requirements
- Heat Dissipation: Adopt forced air cooling or water cooling systems to ensure the junction temperature ≤125℃; the thermal resistance of the heat sink must match the ultra-high power loss of the module.
- 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; shielded wires shall be used for gate control lines, and the drive unit shall be installed close to the module to reduce the inductance of the drive circuit.
Maintenance Key Points
- Regularly inspect the heat dissipation system (fans, water pumps, heat sinks) and clean dust and scale to ensure heat dissipation efficiency.
- Monitor the on-state voltage drop, gate voltage and temperature; troubleshoot module or drive faults in a timely manner if abnormalities occur.
- Conduct insulation tests in accordance with ABB specifications to prevent short circuits caused by insulation aging.
- Regularly calibrate the gate drive timing and protection thresholds to ensure matching with the module.
