Switch Mode Power Supplies

Switch Mode Power Supplies Description

Switch Mode Power Supplies (SMPS) are widely used in modern electronic and electrical systems to efficiently convert and regulate electrical power. Unlike conventional linear power supplies, SMPS technology uses high-frequency switching to achieve improved efficiency, compact size, and reduced power losses. Magnetic components are at the core of these systems, supporting energy transfer, voltage conversion, electrical isolation, energy storage, current filtering, and EMI suppression.

Key magnetic components used in SMPS include high-frequency transformers, SMPS transformers, power inductors, PFC inductors, output chokes, common-mode chokes, and EMI filter coils. Transformers provide voltage conversion and isolation, while inductors and chokes help control current, reduce ripple, and filter unwanted switching components. EMI filters help suppress conducted noise generated by high-frequency switching circuits.
