## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Circuit Issues
- Pitfall : Insufficient gate drive current causing slow switching and increased losses
- Solution : Implement dedicated gate driver IC with peak current capability >2A
- Pitfall : Lack of negative bias during turn-off leading to parasitic turn-on
- Solution : Provide -5V to -15V negative supply for turn-off stability
Thermal Management Problems
- Pitfall : Inadequate heat sinking causing thermal runaway
- Solution : Calculate thermal impedance and select heat sink with Rth<0.1°C/W
- Pitfall : Poor thermal interface material application
- Solution : Use high-performance thermal grease with proper application thickness (0.05-0.1mm)
Overcurrent Protection
- Pitfall : Delayed short-circuit protection destroying IGBT
- Solution : Implement desaturation detection with response time <5μs
- Pitfall : Inadequate snubber circuits causing voltage overshoot
- Solution : Design RCD snubber networks based on stray inductance measurements
### Compatibility Issues with Other Components
