Design considerations
- Switching losses versus conduction losses dominate device choice, so need to select MOSFETs based on RDS(on) and QG/Qoss trade-off.
- High-side gate driving and layout become critical for reliability. Bootstrap / driver must handle dV/dt, dead-time and Miller turn-on immunity. Poor layout or weak drivers lead to shoot-through and EMI.
- Regenerative operation drives DC bus and protection design so braking and bidirectional power flow require bus overvoltage handling (TVS, braking or control) and sufficient capacitor sizing.
- Fast edges require controlled gate resistance, snubbing and tight layout to avoid overshoot, false turn-on and compliance issues.
