## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues
- *Pitfall*: Insufficient gate drive current causing slow switching and increased losses
- *Solution*: Implement dedicated gate driver IC with adequate peak current capability (2-4A recommended)
Thermal Management
- *Pitfall*: Inadequate heatsinking leading to thermal runaway
- *Solution*: Use thermal interface materials with low thermal resistance and proper mounting torque
Overvoltage Protection
- *Pitfall*: Voltage spikes during switching causing device failure
- *Solution*: Implement snubber circuits and careful layout to minimize parasitic inductance
EMI Concerns
- *Pitfall*: High dv/dt causing electromagnetic interference
- *Solution*: Use gate resistors to control switching speed and implement proper shielding
### Compatibility Issues with Other Components
Gate Drivers
- Compatible with industry-standard IGBT drivers (IR21xx series recommended)
- Requires negative bias capability for reliable turn-off
- Gate voltage range: -10V to +15V (absolute maximum)
DC-Link Capacitors
- Low-ESR film or electrolytic capacitors required
- Must withstand high ripple current (calculate based on application requirements)
- Recommended: 470μF to 1000μF per kW of output power
Current Sensors
- Hall-effect sensors recommended for isolation
- Shunt resistors require careful common-mode voltage management
- Ensure bandwidth exceeds switching frequency by 10x
Microcontrollers
- PWM outputs must have sufficient resolution for precise control
- Dead-time generation capability essential
- Fault monitoring inputs required for protection circuits
### PCB Layout Recommendations
Power Stage Layout
- Keep DC-link capacitor connections as short as possible (<20mm)
- Use wide copper pours for high-current paths (minimum 2oz copper recommended)
- Maintain minimum clearance: 8mm for 600V applications
