## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues
- *Pitfall*: Insufficient gate drive current causing slow switching and excessive losses
- *Solution*: Implement dedicated gate driver ICs with peak current capability >2A
- *Pitfall*: Voltage overshoot during turn-off due to stray inductance
- *Solution*: Use low-inductance gate drive loops and consider negative turn-off voltage
Thermal Management
- *Pitfall*: Inadequate heatsinking leading to thermal runaway
- *Solution*: Calculate thermal impedance and select heatsink with Rth<1.5°C/W
- *Pitfall*: Poor thermal interface material application
- *Solution*: Use high-performance thermal grease and proper mounting torque (0.6-0.8Nm)
### Compatibility Issues with Other Components
Gate Driver Compatibility
- Requires isolated gate drivers with 15V typical supply voltage
- Compatible with common driver ICs: IR2110, FAN7392, 2ED020I12-F2
- Ensure common-mode transient immunity >50kV/μs for high-noise environments
DC-Link Capacitors
- Must withstand high ripple current (calculate based on switching frequency)
- Recommended: Film capacitors for high-frequency applications
- Electrolytic capacitors require careful ESR consideration
Current Sensing
- Shunt resistors must handle peak currents up to 20A
- Hall-effect sensors recommended for isolation requirements
- Ensure proper bandwidth (>100kHz) for accurate current measurement
### PCB Layout Recommendations
Power Circuit Layout
- Minimize loop area in high-current paths (DC bus and output phases)
- Use thick copper pours (≥2oz) for power traces
- Place decoupling capacitors as close as possible to module terminals
- Maintain creepage/clearance distances: 8mm for 600V applications
Gate Drive Layout
- Keep gate drive traces short and direct (<3cm ideal)
- Implement separate ground planes for power and
