EMC compliance is essential for power modules in commercial and industrial applications. This guide covers conducted and radiated emission control.

Input filtering is critical for conducted emissions. Use X and Y capacitors, common mode chokes, and differential mode inductors as recommended.

Output filtering may be needed for sensitive loads. Ceramic capacitors provide high-frequency filtering close to the load.

PCB layout affects EMC performance. Keep switching loops small, use ground planes, and separate noisy and sensitive circuits.

Shielding may be required for high-power or sensitive applications. Metal enclosures provide effective radiated emission control.
