6. Selection Suggestions
- Voltage/Current Matching: Ensure compatibility with system voltage (4500 V DC bus) and current requirements (≥3500 A continuous).
- Cooling System: Use liquid cooling for full-load operation (recommended flow rate: 10–15 L/min).
- Control Interface: Verify gate driver compatibility (±15 V input, isolated signal lines).
- Redundancy Planning: For critical systems, deploy parallel modules with current sharing inductors.
7. Precautions
- Thermal Management: Maintain case temperature ≤85°C; derate by 10% for ambient temperatures >40°C.
- Assembly Torque: Follow ABB’s torque specifications (12–15 N·m for clamping bolts).
- Surge Protection: Install transient voltage suppression (TVS) diodes for overvoltage protection.
- Storage Conditions: Store in dry environments (≤50% humidity) with anti-static packaging.
