## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues
- Pitfall : Inadequate gate drive current leading to slow switching and increased losses
- Solution : Implement gate drivers with minimum ±4A peak current capability
- Pitfall : Excessive gate resistor values causing switching speed reduction
- Solution : Optimize RG values between 1-5Ω based on EMI and switching loss trade-offs
Thermal Management Problems
- Pitfall : Insufficient heatsink sizing resulting in thermal runaway
- Solution : Calculate thermal impedance requirements for worst-case operating conditions
- Pitfall : Poor thermal interface material application
- Solution : Use high-performance thermal grease with proper application technique
Protection Circuit Omissions
- Pitfall : Missing short-circuit protection
- Solution : Implement desaturation detection with soft shutdown capability
- Pitfall : Inadequate overcurrent protection
- Solution : Use current sensors with fast response time (<2μs)
### Compatibility Issues with Other Components
Gate Driver Compatibility
