## 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 peak current capability ≥4A and proper gate resistor selection (2.2-10Ω range)
*Pitfall*: Voltage spikes during turn-off causing device stress
*Solution*: Use negative gate bias (-5 to -15V) during off-state and implement snubber circuits
Thermal Management
*Pitfall*: Insufficient heatsinking causing thermal runaway
*Solution*: Calculate thermal impedance requirements and use forced air/liquid cooling for currents >100A
*Pitfall*: Improper thermal interface material application
*Solution*: Use high-performance thermal grease (λ ≥ 3W/mK) and proper mounting torque (2.0-3.0N·m)
Protection Circuitry
*Pitfall*: Lack of overcurrent protection during short-circuit conditions
*Solution*: Implement desaturation detection with blanking time (2-3μs) and soft shutdown
*Pitfall*: Inadequate overvoltage protection
*Solution*: Use DC-link snubbers and active clamping circuits
