## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues:
- Pitfall : Inadequate heat sink design leading to thermal runaway
- Solution : Implement liquid cooling with minimum flow rate of 8 L/min and temperature monitoring
- Pitfall : Poor thermal interface material application
- Solution : Use high-performance thermal grease with proper application thickness (50-100μm)
Gate Drive Challenges:
- Pitfall : Insufficient gate drive power causing slow switching and increased losses
- Solution : Use dedicated gate driver ICs with ±15V supply and 35W peak power capability
- Pitfall : Voltage overshoot during turn-off
- Solution : Implement active clamping circuits and optimize gate resistor values (2-5Ω recommended)
### Compatibility Issues with Other Components
Gate Driver Compatibility:
- Requires isolated gate drivers with minimum 10kV isolation rating
- Compatible with ABB's HVDC series gate drivers
- Ensure common-mode transient immunity >50kV/μs
DC-Link Capacitors:
- Must withstand high ripple currents (≥200A RMS)
- Recommended: Film capacitors with low ESR
- Voltage rating: Minimum 4500V DC
Current Sensors:
- Hall-effect sensors with 3500V isolation minimum
- Bandwidth: >100kHz for accurate current measurement
- Accuracy: ±1% for proper protection
### PCB Layout Recommendations
Power Circuit Layout:
- Maintain minimum 15mm creepage distance between high-voltage nodes
- Use 4oz copper thickness for power traces
- Implement symmetric DC-link capacitor placement
- Keep gate drive loops compact (<50mm total length)
