## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues
- *Pitfall*: Insufficient gate drive current leading to slow switching and excessive losses
- *Solution*: Implement gate drivers with peak current capability ≥4A and proper negative turn-off voltage (-5 to -15V)
Thermal Management Problems
- *Pitfall*: Inadequate heatsink design causing thermal runaway
- *Solution*: Use thermal interface materials with thermal resistance <0.1°C/W and forced air/liquid cooling
Overvoltage Stress
- *Pitfall*: Voltage spikes during turn-off exceeding maximum ratings
- *Solution*: Implement RCD snubber circuits and optimize busbar layout to minimize stray inductance
### Compatibility Issues with Other Components
Gate Driver Compatibility
- Requires isolated gate drivers with minimum 2500V isolation rating
- Compatible with industry-standard drivers from Infineon, Texas Instruments, and Silicon Labs
DC-Link Capacitors
- Must use low-ESR film or ceramic capacitors in parallel with electrolytic types
- Recommended capacitance: 1-2μF per amp of rated current
Current Sensors
- Hall-effect sensors preferred over shunt resistors to maintain isolation
- Rogowski coils suitable for high-frequency current measurement
### PCB Layout Recommendations
Power Circuit Layout
- Keep DC bus connections as short and wide as possible (minimum 50mm width for 160A)
- Maintain minimum 8mm creepage distance between high-voltage nodes
- Use multiple vias for current sharing in multilayer boards
Gate Drive Layout
- Route gate drive traces separately from power traces
- Keep gate loop area minimal to reduce parasitic inductance
- Place gate resistors as close to module terminals as possible
