- Solution : Implement gate drivers capable of ±20A peak current with proper decoupling
Thermal Management Problems
- Pitfall : Insufficient heatsinking causing thermal runaway
- Solution : Use thermal interface materials with thermal resistance <0.05°C/W and forced air cooling
Voltage Spikes and Overshoot
- Pitfall : Excessive voltage spikes during turn-off damaging the device
- Solution : Implement snubber circuits and optimize busbar layout to minimize stray inductance
EMI Concerns
