## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Gate Driving
- *Problem*: Insufficient gate drive current leading to slow switching and increased losses
- *Solution*: Implement dedicated gate driver ICs with peak current capability >10A
Pitfall 2: Poor Thermal Management
- *Problem*: Overheating due to insufficient heatsinking
- *Solution*: Use forced air cooling or liquid cooling with thermal interface material
Pitfall 3: EMI Issues
- *Problem*: High dv/dt causing electromagnetic interference
- *Solution*: Implement snubber circuits and proper shielding
### Compatibility Issues
Gate Driver Compatibility
- Requires negative turn-off voltage (-15V recommended) for reliable operation
- Compatible with most industrial IGBT drivers (e.g., INFINEON 1ED系列)
DC-Link Capacitors
- Must withstand high ripple currents
- Recommended: Low-ESR film capacitors or aluminum electrolytic capacitors
Current Sensors
- Compatible with Hall-effect sensors and shunt resistors
- Ensure proper isolation for high-side switches
### PCB Layout Recommendations
Power Circuit Layout
- Keep DC-link capacitor connections as short as possible
- Use wide copper pours for high-current paths (minimum 70mm width for 400A)
- Maintain adequate creepage and clearance distances (≥8mm for 600V)
Gate Drive Layout
- Implement separate ground planes for power and control circuits
- Route gate drive signals away from high-voltage switching nodes
- Use twisted-pair or coaxial cables for gate connections in external drive scenarios
Thermal Management
- Provide adequate copper area for thermal vias to heatsink
- Use thermal interface pads with high thermal conductivity (>3 W/mK)
- Ensure even pressure distribution during module mounting
