Core Viewpoint - The semiconductor equipment power supply industry is experiencing rapid growth driven by policy support and downstream demand, with domestic companies making breakthroughs in key areas like RF power supplies, although high-end products still rely on imports [3][4]. Product Definition and Statistical Scope - The article focuses on RF power supplies and DC power supplies used in the semiconductor industry, defining RF power supplies as capable of generating fixed frequency sine wave voltages within the RF range (approximately 3KHz to 300GHz) with power ratings from 0.3 to 15kW [2]. Current Industry Status - The Chinese semiconductor equipment power supply industry is growing rapidly due to policy support and demand, with domestic firms achieving breakthroughs in RF and high-voltage DC power supplies. However, high-end products still depend on imports, and the self-sufficiency rate of core components remains low [3]. - The global market is dominated by companies from the US, Europe, and Japan, with American firms like MKS and AE holding significant market shares in RF power supplies. Japanese and German companies monopolize the high-end sector, leveraging advanced technologies for superior efficiency and power density [3][4]. Technological Evolution - The industry is evolving towards higher frequency, integration, and intelligence, with increased penetration of SiC/GaN devices enhancing energy efficiency. Domestic companies face three main challenges: reliance on imported high-end RF amplifiers, discrepancies in impedance matching precision, and insufficient stability in microsecond-level response for wafer manufacturing power supplies [4]. Development Trends - SiC and GaN wide bandgap semiconductor materials are rapidly replacing traditional silicon-based devices, significantly enhancing power supply performance. These materials offer higher breakdown voltages, lower on-resistance, and ultra-high frequency switching characteristics, achieving power density levels 1.5 times higher than domestic products [6]. - Power management systems are integrating AI algorithms and IoT technologies for dynamic energy efficiency optimization and remote intelligent control, including real-time voltage/frequency adjustments and embedded sensors for predictive maintenance [6]. - Global carbon neutrality goals are driving upgrades in power supply efficiency standards, with China's "dual carbon" policy mandating a conversion efficiency of ≥ 95%, pushing companies to focus on zero standby loss and renewable energy compatibility [6]. Market Scale Analysis - The global semiconductor equipment power supply market is projected to reach $1,208.9 million in 2024, with expectations to grow to $3,364.3 million by 2031, reflecting a compound annual growth rate (CAGR) of 16.52% [7]. - The Chinese market is rapidly evolving, with a projected size of $343.8 million in 2024, accounting for approximately 28.4% of the global market, and expected to reach $1,036.1 million by 2031, increasing its share to 30.8% [8]. Competitive Landscape - Major global manufacturers include Advanced Energy, 万机仪器, 康姆艾德, DAIHEN Corporation, and 通快, with the top five companies expected to hold over 44.38% of the market share in 2024. Competition is anticipated to intensify, particularly in the Chinese market [8]. Policy Analysis - Internationally, the US has imposed restrictions on the export of power supplies for devices below 14nm to China, impacting the supply of high-end power equipment. In contrast, Japan and South Korea are implementing national strategies to bolster their semiconductor industries, enhancing local demand for power supply equipment [12][13]. - Domestically, China is prioritizing semiconductor equipment power supplies in its "Made in China 2025" and "14th Five-Year Plan," aiming to increase the localization rate of SiC/GaN power modules by 2025 to break the monopoly of US and Japanese firms [14].
