EMC Compliance for Power Modules
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.
