## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues
- *Pitfall*: Inadequate heatsinking leading to premature thermal shutdown
- *Solution*: Implement forced air cooling (≥3 m/s airflow) and use thermal interface materials with thermal resistance <0.1°C/W
Gate Drive Problems
- *Pitfall*: Insufficient gate drive current causing slow switching and increased losses
- *Solution*: Use gate drivers with peak current capability ≥4A and implement active Miller clamp
Overvoltage Stress
- *Pitfall*: Voltage spikes during turn-off exceeding maximum ratings
- *Solution*: Implement snubber circuits and optimize DC bus layout to minimize stray inductance
### Compatibility Issues
Gate Driver Compatibility
- Required gate drive voltage: +15V/-8V to +20V/-15V
- Compatible drivers: IR2110, IR2130, 2ED300C17-S families
- Incompatible with: Single-supply gate drivers without negative turn-off capability
Sensor Integration
- Built-in NTC thermistor: 10kΩ at 25°C
- Compatible with standard temperature monitoring ICs
- Requires isolation for high-side temperature sensing
DC Bus Components
- Recommended DC link capacitors: Low-ESR film or electrolytic capacitors
- Bus bar design must accommodate module terminal configuration
- Incompatible with: High-inductance bus structures
### PCB Layout Recommendations
Power Circuit Layout
- Keep DC bus connections as short and wide as possible (<30mm recommended)
- Use multilayer PCB with dedicated power and ground planes
- Maintain minimum 8mm creepage distance between high-voltage traces
