In 2025, toChatGPT、 Generative AI applications represented by Deepseek have deeply penetrated thousands of industries, driving the growth of global computing power. The power density of AI server cabinets has also skyrocketed, from 10-20kW in the past to hundreds of kilowatts or even megawatts. The traditional UPS power supply architecture has low conversion efficiency, which restricts the development of AI computing power. Therefore, how to provide energy for these "computing beasts" more efficiently, stably, and economically has become the core pain point of the entire industry.

The typical link of traditional UPS solution is:Mains power → UPS (AC/DC-DC/AC) →PDU(Power distribution unit) → Server built-in power supply (AC/DC)After multiple AC/DC conversions, the energy loss is relatively high, and the overall power supply efficiency is usually less than 90%, which is difficult to meet the pursuit of energy efficiency in the AI era.

± 400V, 800V, 1500V (future direction)HVDCArchitecture can significantly improve end-to-end energy efficiency by reducing conversion steps, and has become the mainstream trend in future AI data centers. Recently, Nvidia released800 VDC Architecture for Next Generation AI InfrastructureClearly proposed the direction of evolution towards 800V DC architecture.

Core value: 800V high-voltage direct current will become the mainstream solution for AI data center power supply in the future due to its efficiency improvement (3-5 percentage points higher than UPS), copper consumption reduction of over 45%, and space optimization of 30%. Among them, NVIDIA proposed to use solid-state transformers（SST）Technology that efficiently converts medium voltage AC power (such as 10kVAC) into 800V DC in one step and feeds it directly into IT racks. The traditional multi-level transformation mode is the cornerstone technology for realizing the "AI computing power factory".

Launched AI for industry testing needsserver power supplyThe full scenario testing solution can meet the testing applications of PSU, Power Shelf, Rack Power, board level power supply, HVDC, BBU, SST, etc. in traditional UPS architecture and 400V/800V/1500V HVDC architecture. The solution has the following customer value:
