The growth in renewable energy sources and applications is expected to further propel the switch mode power supply market. Renewable energy, characterized by its sustainability and minimal environmental impact, is harnessed from naturally replenishable sources. Switch mode power supply transformers play a crucial role in efficiently converting and managing electrical energy in renewable energy systems, facilitating the transformation of variable and intermittent sources like solar and wind power into stable and usable electrical power. According to a report by the International Energy Agency in March 2023, renewable energy sources, including solar and wind power, are projected to meet over 90% of the global increase in energy demand by 2025. This trend is set to drive the demand for switch mode power supply transformers.

Leading companies in the switch mode power supply transformers market are developing innovative products, such as space-grade planar transformers, to meet stringent requirements by delivering high efficiency, reduced size, and enhanced thermal management. For instance, in May 2024, Vishay Intertechnology Inc., a US-based semiconductor manufacturing company, launched a new series of low-profile, space-grade planar transformers designed for power conversion applications. These transformers are suitable for use in switch mode power supplies, DC/DC converters, and AC/DC converters. Part of the SGTPL-2516 series, these transformers stand out for their lower cost, compact size, and higher density compared to traditional planar transformers.

In April 2024, Mitsubishi Electric Corporation, a Japan-based provider of switch-mode power supply (SMPS) transformers, partnered with Hitachi Ltd. Under this partnership, Mitsubishi Electric will transfer its distribution transformer business to Hitachi Industrial Equipment Systems, thereby strengthening Japan's power distribution network. Hitachi Ltd., a multinational conglomerate based in Japan, will leverage this collaboration to enhance its capabilities in the power distribution sector.

Major companies operating in the switch mode power supply transformers market are ABB Group, Omron Corporation, Premier Magnetics, Salcomp plc, Schneider Electric SE, Siemens AG, Sumida Corporation, Tamura Corporation, TDK Corporation, Triad Magnetics, Butler Winding Inc., Bel Fuse Inc., Delta Electronics Inc., Murata Manufacturing Co. Ltd., Eaton Corporation plc, Goh Synergy Transformers Pte Ltd., Coil Winding Specialist Inc., Tri-Mag Inc., Wabash Transformer Inc., Pacific Transformer Corp.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have increased the cost of imported core materials, copper windings, semiconductor switches, and magnetic components used in SMPS transformers, particularly those sourced from China and Southeast Asia. Industrial, consumer electronics, and communications sectors face higher production costs and longer supply cycles. Nonetheless, tariffs are stimulating regional manufacturing of magnetic components, encouraging localized sourcing, and driving innovation in energy-efficient transformer designs that enhance long-term manufacturing independence.

Switch-mode power supply (SMPS) transformers are a specific type of transformer employed in various devices, notably in computers. These transformers are commonly utilized in commercial and industrial settings to power electronic equipment like medical devices, communication devices, and commercial power supplies. Their primary function lies in regulated power supply, where they play a crucial role in stepping up or down voltage or current and providing isolation between the input and output sides.

There are several types of switch-mode power supply transformers, including AC to DC, DC to AC, DC to AC, and AC to DC. The AC to DC variant, for instance, is designed to convert alternating current (AC) main power into direct current (DC) output voltage with high efficiency. Upon powering up, the AC main power undergoes filtration through a capacitor, transforming it from AC voltage to unregulated DC voltage using rectifiers. The switch-mode transformer then converts this unregulated DC voltage into a regulated DC output voltage at various levels using a regulator. These transformers are crucial in different voltage categories, such as distribution voltage, sub-transmission voltage, high voltage transmission, extra high voltage transmission, and ultra-high voltage transmission. They cater to diverse end-users, including consumer electronics, communications, industrial applications, and more.North America was the largest region in the switch mode power supply transformers market in 2025.
