## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues
- Pitfall : Inadequate heat sinking leading to thermal runaway
- Solution : Implement forced air or liquid cooling with thermal interface materials
- Monitoring : Utilize integrated NTC for real-time temperature tracking
Gate Drive Problems
- Pitfall : Insufficient gate drive current causing slow switching
- Solution : Use dedicated gate driver ICs with peak current >10A
- Protection : Implement DESAT detection and soft turn-off circuits
Voltage Overshoot
- Pitfall : Excessive DC-link inductance causing voltage spikes
- Solution : Minimize busbar inductance and use snubber circuits
- Layout : Keep DC-link capacitors close to module terminals
### Compatibility Issues
Gate Driver Compatibility
- Requires gate drivers supporting ±20V supply with negative turn-off voltage
- Compatible with: 1ED020I12-F2, 2ED300C17-S, ACPL-332J
DC-Link Capacitors
- Recommended: Film capacitors with low ESR/ESL
- Avoid: Electrolytic capacitors with high inductance
Current Sensors
- Compatible with: LEM IT series, Allegro ACS series hall-effect sensors
- Shunt resistors require high-bandwidth isolation amplifiers
### PCB Layout Recommendations
Power Circuit Layout
- Use thick copper layers (≥2 oz) for power traces
- Minimize loop area in power paths
- Place DC-link capacitors within 30mm of module terminals
- Implement symmetrical layout for parallel modules
Gate Drive Layout
- Keep gate drive loops compact and isolated from power circuits
- Use twisted pair or coaxial cables for gate connections
