As AI racks consume more power, how should the power supply chain be upgraded?
From large model training to the deployment of AI inference applications, computing demand is growing rapidly. At the same time, data centers are undergoing major changes: GPU power consumption is increasing, rack power density is rising, and power supply systems are moving from behind the scenes to a critical position.
For 10MW-level or even larger-scale AIDC projects, the focus is no longer just whether there is enough power. The real question is whether electricity can be delivered to server racks efficiently and reliably.
The longer the power supply path and the more conversion stages involved, the greater the losses and heat dissipation pressure. These factors further affect electricity costs, system energy efficiency, and future expansion capability.
As computing power continues to grow, more AIDC projects are beginning to ask: should the power supply architecture be upgraded accordingly?
High-Efficiency HVDC Power Supply Solution for Computing Centers
To address this industry challenge, BOCO Electronics has launched its 800V HVDC architecture, which acts like a direct “highway” carrying power straight to server racks.
After utility power, solar power, energy storage, and other energy sources are connected, the system delivers power to AI server racks through a shorter supply path. By reducing intermediate conversion stages, it enables electricity to enter computing loads with higher efficiency.
Compared with traditional multi-stage conversion solutions, the HVDC architecture delivers the following advantages:
1. Higher Efficiency
Compared with traditional multi-stage conversion, the HVDC architecture reduces intermediate conversion stages. The system’s peak efficiency exceeds 99%, improving power conversion performance and reducing transmission losses.
2. Significant Energy Efficiency Improvement
In typical application scenarios, compared with traditional architectures, the overall system energy efficiency can be improved by up to 15%, helping reduce long-term operating costs.
3. Flexible Configuration
The solution provides multiple power options, including 625kW, 750kW, and 1000kW, allowing flexible matching according to project scale.
4. Smooth Expansion
The system can be flexibly expanded as the number of racks increases and load demand grows. This helps reduce resource waste during the initial construction stage while reserving sufficient space for future development.
Beyond Efficiency: Reliability Matters Just as Much
Once computing tasks are started, continuous operation becomes essential. While pursuing higher efficiency, the BOCO Electronics 800V HVDC architecture also places strong emphasis on system reliability.
Intelligent Protection
The system supports modular parallel operation, hot-swappable maintenance, and multiple protection mechanisms. Its modular and hot-swappable design makes later-stage maintenance faster and more controllable. When abnormalities occur, key protection mechanisms can be triggered in time, enabling faster fault location and easier handling, while minimizing the impact of maintenance on system operation.
Scenario Adaptability
In integrated scenarios such as solar-storage-computing applications, the system supports green energy access and energy storage backup, meeting the flexible power supply needs of next-generation data centers.
Currently, this solution has been validated in multiple overseas solar-storage-computing and complex power supply projects, fully demonstrating its system capabilities in green energy integration and high-density load power supply.
In the AI era, computing power is becoming a new form of productivity. With the design concept of “fewer conversion stages, higher efficiency, easier expansion, and greater reliability,” the BOCO Electronics 800V HVDC architecture provides stable and reliable energy support for high-density computing centers.
If you are planning a new AIDC project or an expansion project, BOCO Electronics welcomes the opportunity to connect with you and explore a more efficient power supply architecture together.
