The following are the latest developments in the uninterruptible power supply (UPS) industry in 2025, summarizing key trends from various dimensions such as technological innovation, market application, and policy standards:

---

⚡ 1、 Breakthrough in core technology innovation

1. Power device upgrade

   • Popularization of SiC/GaN devicesSilicon carbide (SiC) and gallium nitride (GaN) power devices significantly improve UPS efficiency and power density. For example, Infineon CoolSiC ™ MOSFET reduces switch losses by 70%, enabling 30kVA UPS efficiency to exceed 96% and reducing volume by 30%. The Delta DPH Gen3 series adopts SiC technology, with a light load efficiency of 97.3% and an ECO mode efficiency of up to 99.3%.

   • Dynamic response optimizationTo cope with millisecond level fluctuations in AI load (30% -160% jump), the new generation UPS integrates supercapacitors (response<10ms), flywheel energy storage (90 second power supply), and lithium batteries to avoid power outages.

2. Diversification of energy storage systems

   • Lithium batteries dominateLithium iron phosphate batteries have become the preferred choice for data centers due to their cycle life of over 1500 times, 10-year maintenance free, and 40% lower lifecycle cost than lead-acid batteries.

   • Hydrogen fuel and supercapacitorsHydrogen fuel cell UPS achieves zero carbon emissions (such as the case of the Israeli medical center), while supercapacitors are used for short-term backup scenarios with a cycle life of over a million times.

   • Hybrid energy storage solutionNingde Times' new patent supports the maintenance of bypass systems, which can maintain UPS under continuous power supply and improve power supply reliability.

3. Intelligent and predictive maintenance
   AI driven UPS shifts from passive power supply to active management:

   • The Huawei iPower system provides a 72 hour advance warning for faults, reducing the average repair time to 30 minutes;

   • Delta DPH Gen3 has built-in AI pre check function, which can analyze the life cycle of key components (such as capacitors and fans) in real time.

�� 2、 Integration of Green Low Carbon and Renewable Energy

1. Upgrading energy efficiency standards

   • China's "15th Five Year Plan" requires UPS energy efficiency levels below level 2 to be prohibited from sale, while the EU's ErP Lot 28 limits no-load power consumption to below 15W, promoting the popularization of liquid cooling technology. Liquid cooled UPS has rapidly increased its penetration rate in data centers, helping to reduce PUE values to below 1.2 (as seen in the case of China Mobile's Yangtze River Delta Cloud Computing Center).

2. PV ESS UPS (Photovoltaic Energy Storage System)

   • The Delta 800V DC bus scheme is directly connected to photovoltaic power generation, with a green power consumption ratio of 65%;

   • The integrated solution of solar power, photovoltaic and energy storage has improved the comprehensive energy efficiency by 18%, and the California power grid has increased the wind power consumption rate by 12% through intelligent UPS clusters.

�� 3、 Scene customization and modular architecture

1. Industrial voltage customization
   Local brands such as Ubishi have launched non-standard voltage UPS (200V-690V) to solve compatibility issues with imported equipment and provide a full lifecycle service network.

2. Modularization has become mainstream

   • The market share is expected to exceed 51.8% by 2026, and Huawei FusionPower will achieve "one cabinet, one megawatt", saving 50% of land occupation;

   • The Weidi Technology EXL series integrates distribution cabinets and micro modules, reducing deployment time from 3 days to 4 hours.

�� 4、 Emerging application scenarios and market growth

1. AI data center drives high power demand
   The explosion of AI computing power has driven the power of single cabinets from 5-10kW to 30-50kW (some up to 100kW), and the UPS power range has been synchronously increased. The estimated market size of China's data center UPS in 2025 is 6.68 billion yuan, with a CAGR of approximately 20% from 2025 to 2028.

2. Going global and cross-border competition

   • Domestic industrial chains such as Kehua and Kesida are accelerating their overseas expansion, and Delta's prefabrication solution has saved 60% of deployment time in Southeast Asian projects;

   • Tesla Megapack energy storage system (1.5MWh capacity) enters the data center market, and supercapacitor manufacturers develop fast charging solutions to compete for short-term backup power share.

⚖️ 5、 Policy and standard updates

• Implementation of the new national standardThe "Uninterruptible Power Supply System (UPS) Part 3" edited by Kehua will come into effect in January 2025, updating requirements such as altitude derating coefficient and total harmonic distortion rate (≤ 8% for public power grid)

• Security certification enhancementMedical and industrial scenarios must comply with CE certification and short-circuit protection standards, and companies such as Ubishi can enhance barriers through patent layout
