## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Circuit Issues
*Pitfall*: Inadequate gate drive current leading to slow switching and increased switching losses
*Solution*: Implement gate drivers capable of delivering 2-3A peak current with proper decoupling
*Pitfall*: Excessive gate resistor values causing Miller plateau issues
*Solution*: Use separate turn-on and turn-off resistors (typically 10-47Ω) for optimal switching control
Thermal Management Problems
*Pitfall*: Insufficient heatsinking resulting in thermal runaway
*Solution*: Calculate thermal impedance and provide adequate heatsinking with thermal interface material
*Pitfall*: Poor PCB layout affecting thermal performance
*Solution*: Use thermal vias and adequate copper area for heat dissipation
Protection Circuit Omissions
*Pitfall*: Lack of overcurrent protection during fault conditions
*Solution*: Implement desaturation detection or current sensing with appropriate response time
