## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues
*Pitfall*: Inadequate heatsinking leading to premature thermal shutdown
*Solution*: Implement forced air cooling with minimum 2.5 m/s airflow or liquid cooling for full current operation
Gate Drive Circuit Problems
*Pitfall*: Excessive gate resistor values causing increased switching losses
*Solution*: Use gate resistors between 2.2-10Ω based on switching frequency requirements
Overvoltage Protection
*Pitfall*: Voltage spikes during turn-off damaging the module
*Solution*: Implement snubber circuits and proper DC bus capacitor placement
