Hey, today we’re talking about HVDC, the superpower partner of AIDC (Artificial Intelligence data centers). Did you know? With the ever-increasing power density of AI chips and servers, the computing power demand of AI data centers is skyrocketing. AIDC power supply and distribution systems will undergo major changes. Traditional UPS power supply architectures will be unable to meet the high-voltage, energy-saving, and low-cost trends of future AI power systems.

High-voltage direct current (HVDC) is a natural fit for this trend, thanks to its simplicity, high conversion efficiency, high voltage levels, and lower capital and operating costs. It’s foreseeable that HVDC penetration will increase significantly in the coming years. HVDC’s impressive performance is first and foremost a true energy saver, capable of boosting conversion efficiency to over 95%, with some even reaching 97%. It’s like installing a super energy saver in a data center. It’s vastly superior to traditional UPS, significantly reducing power usage effectiveness (PUE) to as low as 1.5. Using HVDC, a data center consuming 100 million kWh annually could save the equivalent of a 2.4MW small hydropower station.

To address reliability: The HVDC system employs a modular, redundant design. This means that even if an individual module encounters a minor issue, the overall system operation remains unaffected.
Furthermore, its direct battery connection architecture enables millisecond-level power switching. This ensures the AI data center is consistently powered with rock-solid stability.

HVDC also offers numerous advantages in terms of space and cost. It occupies 30% to 40% less space than UPS and can reduce equipment procurement costs by 15% to 20%. Using 800V HVDC can also reduce copper cable requirements by 45%, significantly reducing material costs. Furthermore, HVDC offers exceptional scalability, easily supporting rack power from 100 kW to over 1 MW. Regardless of the expansion of the AI ​​data center, it can perfectly keep pace.

If data is the new gold, then data centers are their ever-growing digital safes. With the proliferation of advanced 5G technology, AI-powered video on demand, and other applications, data centers are becoming increasingly crucial. To ensure 24/7 availability for data center operations, Hotson’s EVHA series high-voltage DC contactors maintain reliable power supply. Featuring a unique encapsulation design, our DC contactors preserve their characteristics over extended periods without risks of gas leakage or related complications. The hermetically sealed insulation concept ensures robust and dependable performance, effectively preventing unexpected downtime while safeguarding both personnel and infrastructure.

HVDC will become a new trend in AIDC power supply and distribution.
