## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Gate Driving
- Issue : Insufficient gate drive current causing slow switching and increased losses
- Solution : Implement gate drivers with peak current capability >10A and proper isolation
Pitfall 2: Thermal Management Failure
- Issue : Inadequate heat sinking leading to thermal runaway
- Solution : Use thermal interface materials with low thermal resistance and forced air/liquid cooling
Pitfall 3: Voltage Spikes During Turn-off
- Issue : Excessive voltage overshoot damaging the module
- Solution : Implement RCD snubber circuits and optimize gate resistor values
### Compatibility Issues
Gate Driver Compatibility
- Requires negative gate voltage (-15V) for reliable turn-off
- Compatible with isolated gate drivers (e.g., INFINEON 1ED系列)
- Maximum gate-emitter voltage: ±20V
DC-Link Capacitors
- Requires low-ESR DC-link capacitors close to module terminals
- Recommended: Film capacitors with high ripple current capability
Current Sensors
- Compatible with Hall-effect sensors and shunt resistors
- Requires isolation for high-side measurements
### PCB Layout Recommendations
Power Circuit Layout
- Minimize loop area between DC-link capacitors and module
- Use thick copper layers (≥2oz) for power traces
- Place decoupling capacitors within 20mm of module pins
Gate Drive Layout
- Keep gate drive traces short and away from power traces
- Implement separate ground planes for gate drive and power circuits
- Use twisted pair or coaxial cables for gate connections if remote mounting
Thermal Management
- Provide adequate copper area for thermal vias under module
- Ensure flat mounting surface with thermal compound
- Maintain clearance for air flow or coolant channels
