The future market prospects of high-frequency switching power supplies are broad,ushering in a golden development period centered on technological innovation,policy driven development,and explosive application scenarios.Based on the latest industry data and trends in 2026,its market prospects can be systematically summarized into the following four dimensions:

　　Market size continues to expand,with China leading global growth

　　The output value of China's high-frequency switching power supply industry has jumped from 192.4 billion yuan in 2015 to 517.4 billion yuan in 2023,with an average annual compound growth rate of 13.16%,far exceeding the global average level.

　　The overall market size of China's switch mode power supply industry is expected to reach 253.2 billion yuan by 2025,with the total market size of power supplies exceeding 368.2 billion yuan,a year-on-year growth of over 9.5%.

　　China occupies about 40%of the global switch mode power supply market,making it the largest producer and consumer country in the world.The Asia Pacific region contributes over 50%of the global market demand.

　　Three core driving forces reshape the market landscape

　　|Driving field|Key application scenarios|Market impact|

　　|AI and Data Centers|800Vdc High Voltage DC Architecture,CRPS Module,Liquid Cooled Power Supply System|Drive Power Density to 1200W/in3,Expected to Achieve 37.3%Market Share of GaN Power Supply in Data Centers by 2030|

　　|New energy vehicles|On board chargers(OBC),DC-DC converters,48V mild hybrid systems|The OBC market has a compound annual growth rate of over 22%,with global GaN charger shipments reaching 23.77 million units by 2025|

　　|5G and Communication Infrastructure|Embedded Power Supply for Micro Base Stations,BBU/RRU Power Supply,Localization Rate of 95%|The annual increase in demand for 5G base station power supply exceeds 15%,driving the explosion of high-frequency magnetic materials and modular power supplies|

　　Technological evolution accelerates,with wide bandgap semiconductors becoming the core engine

　　GaN(Gallium Nitride):dominates the medium and low voltage(<1000V)market,with an estimated global GaN power semiconductor market size of$4.15 billion by 2030 and a CAGR of over 30%;High power GaN chargers will achieve a CAGR of 17.3%from 2026 to 2032.

　　SiC(silicon carbide):dominates high voltage(>1200V)scenarios,with photovoltaic inverters and charging stations achieving efficiencies exceeding 97%,promoting the popularization of system level magnetic integration and liquid cooling solutions.

　　Digital Intelligence:AI algorithms enable dynamic frequency regulation,predictive maintenance,and energy efficiency optimization.Companies such as Huawei and Xingu have deployed"power+AI"intelligent monitoring systems.

　　Policies and standards force industrial upgrading

　　China GB 20943-2025:2027 is mandatory and requires:

　　Overall efficiency≥90%(kilowatt level power supply)

　　Standby power consumption≤0.3W

　　Mandatory adoption of active PFC and electrolytic capacitor design

　　International benchmarks:EU ErP Lot 27,US DOE Level VII promote comprehensive compliance of export enterprises and accelerate the export of high-end products.

　　Competitive landscape:domestic substitution accelerates,leading enterprises differentiate

　　Future challenges:

　　High threshold for GaN/SiC device driver circuit design

　　The cost of high-frequency magnetic materials(nanocrystals)is still 3-5 times that of silicon-based materials

　　Fragmentation of digital power protocols and lack of unified ecological standards

　　High frequency switching power supplies have evolved from"basic power supply units"to intelligent energy nodes,and their market prospects depend not only on technical parameters,but also on whether they can deeply collaborate with AI,new energy,and digital infrastructure.From 2026 to 2030,the industry will enter the era of"high density,high efficiency,and high intelligence",and Chinese enterprises with material,algorithm,and system integration capabilities are expected to dominate the new global order.
