## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues
- Pitfall : Inadequate gate drive current leading to slow switching and increased losses
- Solution : Implement gate drivers with peak current capability ≥10A and proper gate resistor selection (2-10Ω range)
Thermal Management
- Pitfall : Insufficient heatsinking causing thermal runaway
- Solution : Use thermal interface materials with thermal resistance <0.1 K/W and forced air/liquid cooling
Overvoltage Protection
- Pitfall : Voltage spikes during turn-off damaging the module
- Solution : Implement snubber circuits and proper DC-link capacitor placement
### Compatibility Issues with Other Components
Gate Driver Compatibility
- Requires isolated gate drivers with ±20V capability
- Compatible with INFINEON 1ED-family gate drivers
- Ensure common-mode transient immunity >50 kV/μs
DC-Link Capacitors
- Must withstand high ripple current (≥50A RMS)
- Recommended: Film capacitors or low-ESR electrolytic capacitors
- Voltage rating should exceed 1200V for 1700V systems
Current Sensors
- Hall-effect sensors recommended for isolation
- Shunt resistors require high-voltage isolation amplifiers
- Rogowski coils suitable for high-frequency current measurement
### PCB Layout Recommendations
Power Circuit Layout
- DC Bus : Use parallel copper planes with minimal loop area
- Gate Drive : Keep gate loop inductance <20 nH using short, wide traces
- Current Paths : Maintain symmetrical layout for parallel devices
Thermal Management
- Heatsink Interface : Ensure flat mounting surface with thermal compound
- Thermal Vias : Implement thermal vias under power terminals
- Spacing : Maintain minimum 3mm creepage distance
