## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Gate Driving
- Issue : Slow switching transitions leading to excessive switching losses
- Solution : Implement negative turn-off voltage (-15V recommended) and optimized gate resistor values (2-10Ω typical)
Pitfall 2: Thermal Management Underestimation
- Issue : Junction temperature exceeding 150°C during overload conditions
- Solution : Proper heatsink sizing with thermal interface material and active cooling for high ambient temperatures
Pitfall 3: DC-Link Capacitor Selection
- Issue : Insufficient capacitance causing voltage overshoot during switching
- Solution : Calculate minimum DC-link capacitance based on maximum current and acceptable voltage ripple
### Compatibility Issues
Gate Driver Compatibility
- Requires isolated gate drivers capable of delivering ±20V gate signals
- Compatible with industry-standard drivers (e.g., INFINEON 1ED系列, TI UCC5350)
Sensor Integration
- Built-in NTC thermistor (100kΩ at 25°C) requires appropriate bias circuits
- Compatible with most microcontroller ADC inputs with proper scaling
Busbar Connections
- Module terminals designed for specific busbar configurations
- Incompatible with standard PCB mounting without custom interface boards
### PCB Layout Recommendations
Power Circuit Layout
- DC-Link Placement : Position DC-link capacitors within 50mm of module terminals
- Gate Drive Routing : Keep gate
