EMI Filtering for SMPS, UPS, and Power Supplies
Switch Mode Power Supplies (SMPS), Uninterruptible Power Supplies (UPS), and modern power electronics are the backbone of today’s digital and industrial infrastructure. From data centers and hospitals to factories and telecom networks, power supplies must deliver clean, stable, and reliable power.
However, high-frequency switching inside these systems generates electromagnetic interference (EMI) that can disrupt nearby equipment, reduce efficiency, and cause compliance failures. This is where EMI/RFI filters play a critical role.
