## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Gate Driving
- Problem : Insufficient gate drive current leading to slow switching and increased losses
- Solution : Implement dedicated gate driver ICs with peak current capability >4A and proper isolation
Pitfall 2: Poor Thermal Management
- Problem : Inadequate heatsinking causing thermal runaway and premature failure
- Solution : Use thermal interface materials with thermal resistance <0.1°C/W and forced air/liquid cooling
Pitfall 3: EMI Issues
- Problem : High dv/dt rates generating electromagnetic interference
- Solution : Implement snubber circuits, proper shielding, and follow high-frequency layout practices
Pitfall 4: Voltage Spikes
- Problem : Parasitic inductance causing destructive voltage overshoot during switching
- Solution : Minimize loop area in power circuits and use appropriate clamping circuits
### Compatibility Issues with Other Components
Gate Driver Compatibility:
- Requires gate drivers capable of delivering ±20V with fast rise/fall times
- Compatible with industry-standard drivers like IR2110, 2ED020I12-F, and similar high-voltage ICs
Sensor Integration:
- Temperature sensors (NTC) require proper signal conditioning and isolation
- Current sensors must handle high di/dt rates without saturation
Control System Interface:
- PWM controllers must provide adequate dead time (typically 2-4μs)
- Isolation requirements: 2500Vrms minimum for safety compliance
### PCB Layout Recommendations
Power Circuit Layout:
- Minimize Loop Area : Keep DC bus capacitor close to module terminals (<20mm)
- Low Inductance Paths : Use wide, parallel copper pours for high-current paths
- Thermal Vias : Implement thermal v
