How do you optimize inverter switching strategy for efficiency and EMC compliance?

Inverter switching optimization balances efficiency, EMC, and performance. Higher switching frequency reduces motor torque ripple and filter size but increases switching losses. Strategies include: Variable switching frequency adapting to operating point, spread-spectrum modulation reducing EMI peaks, optimized dead-time minimizing distortion, active gate drive controlling di/dt and dV/dt, soft-switching topologies for loss reduction, and filter design for conducted and radiated emissions. SiC devices enable higher switching frequency with lower loss penalty. EMC validation per CISPR 25 and vehicle-level testing ensures compliance. Trade-offs require system-level optimization.
