Switch Mode Power Supply Transformers Market Seen Topping $2.44 Billion by 2030

The global switch mode power supply transformers market is projected to pass $2.44 billion by 2030, driven by demand for smaller, more efficient power components in consumer electronics, electric vehicles and industrial automation. North America is expected to lead the market, while AC to DC transformers remain the largest product segment.

Why it matters: - The switch mode power supply transformers market is becoming a bigger part of the power electronics supply chain as manufacturers push for smaller, more efficient power conversion. - The market is projected to surpass $2 billion by 2030 and exceed $2.44 billion by 2030. - The category is expected to grow at a 5% CAGR through 2030. - The market remains a niche slice of the broader transformer industry, which is forecast to reach about $102 billion by 2030. - Within the electrical and electronics sector, switch mode power supply transformers are expected to account for about 0.04% of total market value by 2030.

What happened: - The Business Research Company published its "Switch Mode Power Supply Transformers Global Market Report 2026 – Market Size, Trends, And Forecast 2026-2035." - The report says consumer electronics, electric vehicles and industrial automation are key demand drivers for switch mode power supply transformers. - North America is projected to remain the leading regional market in 2030 at $0.88 billion, up from $0.72 billion in 2025. - The United States is expected to be the largest country market in North America, at $0.70 billion in 2030, up from $0.58 billion in 2025.

The details: - Consumer devices such as smartphones, laptops, wearables, gaming consoles, networking equipment and smart home products need compact transformers that reduce size, weight and energy loss. - The report assigns consumer electronics-driven demand about 2.3% annual growth. - EV production and Industry 4.0 deployments are lifting demand for transformers used in onboard chargers, battery management systems, industrial robotics, programmable logic controllers and automated machinery. - That trend contributes about 2.0% to yearly market expansion. - Energy-efficiency rules and demand for higher power density are supporting use in telecommunications, renewable energy, data centers, medical equipment, aerospace electronics and LED lighting. - The report links those trends to roughly 1.9% annual growth. - By transformer type, AC to DC is expected to lead the market in 2030 with 41% share, equal to about $1 billion. - The market also includes DC to DC, DC to AC and AC to AC transformer segments. - By voltage level, the market is split across distribution voltage, sub-transmission voltage and high-voltage transmission. - By end user, the market covers consumer electronics, communications, industrial and other specialized applications.

Between the lines: - The report points to a market being shaped less by one megatrend than by several overlapping shifts: miniaturization, electrification, factory automation and energy efficiency. - Planar transformer technology stands out as a key design trend because it supports smaller form factors and higher power density. - In April 2026, Bourns introduced the SM91270AL and SM91271AL automotive-grade planar transformers for gate driver power applications. - The products use a low-profile EE8.5 platform and offer reinforced insulation rated to 850 VDC and 6000 VDC Hi-Pot isolation. - The report says the market is moderately fragmented, with the top 10 companies accounting for 21% of 2025 revenue. - TDK Corporation held the largest share in 2025 at 4%, tied with Murata Manufacturing Co., Ltd.

What's next: - The report expects AC to DC and DC to DC segments to add about $0.2 billion each in value from 2025 to 2030. - DC to AC and AC to AC segments are each projected to add about $0.1 billion over the same period. - Wide-bandgap semiconductors, high-frequency conversion architectures, intelligent power management and compact transformer designs are expected to drive further growth. - North America should keep its regional lead as next-generation telecom infrastructure, industrial power supplies and energy-efficient components expand. - Companies are focused on miniaturized transformers, planar designs, advanced magnetic materials and automated winding to protect margins and share.

The bottom line: - The market is moving from a specialty component category toward a core enabler of efficient, compact power systems across electronics, mobility and industrial automation.
