Modular Rack Power Infrastructure with Busbar and BBU
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power infrastructure in data centers is often customized and expensive, requiring significant time and resources to adapt to changes in server configurations, as it is designed for the entire data center rather than individual racks, leading to inefficiencies and increased deployment times.
Innovation Solution
A scalable and modular rack-level power infrastructure that includes a power distribution unit (PDU) capable of receiving AC power, outputting DC power to a busbar, and incorporating a battery backup unit (BBU) for redundancy, allowing for modular scaling and customization to meet specific rack-server power needs, reducing design and implementation time, and potentially lowering costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power infrastructure is designed according to the power needs of the entire data center, then the power infrastructure can provide centralized power distribution, but it requires significant time and resources to adapt to changes in server configurations and increases deployment time
Solution Approach 1:
The power infrastructure is segmented into rack-level modular units, each capable of independent operation. This allows individual racks to be configured and deployed independently without affecting the entire data center, enabling faster adaptation to server configuration changes and reducing overall deployment time.
Solution Approach 2:
The modular rack-level power infrastructure enables dynamic reconfiguration of power distribution as server needs change. New racks can be added or existing ones modified without requiring centralized reconfiguration, making the system adaptable to changing server configurations while maintaining operational efficiency.
2Adaptability or versatility
If the power infrastructure includes customized elements to meet specific data center operational and environmental parameters, then the power needs can be precisely met, but the customized elements increase deployment time and cost
Solution Approach 1:
The rack-level power modules are designed as universal units that can be configured to meet different operational and environmental parameters through standardized interfaces. This allows the same modular component to serve multiple data center requirements without requiring custom-designed elements, reducing both deployment time and cost while maintaining precision in meeting power needs.
3Ease of operation
If the power infrastructure is designed for the entire data center rather than individual racks, then centralized power distribution is achieved, but it increases the cost and complexity of the system
Solution Approach 1:
The system segments power distribution into independent rack-level modules, each with its own power management capabilities. This reduces overall system complexity by distributing intelligence to modular units rather than requiring a complex centralized control system, while still achieving coordinated power distribution across the data center.

AI summary
In accordance with the present disclosure, a scalable and modular rack-level power infrastructure is described. The power infrastructure may include a power distribution unit (PDU), which receives alternating current (AC) power from an external power source. The PDU may be coupled to a busbar and output DC power to the busbar. The busbar may be coupled to a server within a rack-server system and provide DC power to the server. Additionally, the infrastructure may include a battery back-up unit (BBU) element coupled to the busbar. The BBU element may charge from and discharge to the busbar.
