## 2. Design Considerations (35%)
### Common Design Pitfalls and Solutions
Thermal Management Issues
- *Pitfall:* Inadequate heatsinking causing thermal shutdown
- *Solution:* Implement proper thermal interface material and calculate required heatsink thermal resistance (Rθsa < 2.5°C/W for full current)
Gate Drive Problems
- *Pitfall:* Insufficient gate drive current leading to slow switching
- *Solution:* Use gate drivers with minimum 2A peak output capability
- *Pitfall:* Excessive gate voltage causing device stress
- *Solution:* Implement Zener clamping to limit VGE to 18V maximum
Overcurrent Protection
- *Pitfall:* Delayed fault response damaging module
- *Solution:* Implement desaturation detection with response time < 2μs
### Compatibility Issues
Gate Driver Compatibility
- Requires negative bias (-5V to -15V) for reliable turn-off
- Compatible with most industrial gate drivers (e.g., IR2110, 2ED020I12-F)
- Incompatible with MOSFET-only drivers lacking negative bias capability
DC Bus Considerations
- Optimal performance with DC link voltage 200-400V
- Requires snubber circuits for voltages above 450V
- DC bus capacitors must handle ripple current > 3A RMS
Control Interface
- TTL/CMOS compatible gate signals (0-15V)
- Requires isolation for high-side switches
- Compatible with most microcontroller PWM outputs
### PCB Layout Recommendations
Power Circuit Layout
- Keep DC bus capacitor connections within 20mm of module terminals
- Use 2oz copper for power traces with minimum 3mm width per amp
- Implement star-point grounding for power and control grounds
- Maintain 8mm creepage distance between high-voltage nodes
Gate Drive Layout
- Route gate drive traces as twisted pairs with ground return
- Keep gate
