Power Supply Subsystem Switching for Flexible Availability Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems in data centers lack flexibility to easily accommodate multiple power supply availabilities at a low cost, making it difficult for data centers to configure power supply structures according to business needs and optimize costs.
Innovation Solution
A power supply system comprising a first sub-system with higher power supply availability and a second sub-system with lower availability, connected by a control unit that allows for independent or interconnected operation, enabling flexible configuration and cost-effective power supply structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single power supply structure is used, then the system is simple and cost-effective, but it cannot provide multiple power supply availabilities to meet different business demands
Solution Approach 1:
The power supply system is divided into multiple independent sub-systems, each with different power supply availabilities (e.g., 2N, N+1, N configurations). Each sub-system can independently serve different business units with varying availability requirements, allowing the overall system to provide multiple availability levels without requiring a single complex unified structure.
Solution Approach 2:
The power supply system is designed to provide multiple functions through a unified architecture that supports different availability configurations. The same physical infrastructure can serve multiple business demands with different availability requirements by dynamically allocating resources and configuring connection relationships between sub-systems.
2Adaptability or versatility
If multiple power supply structures are deployed to meet different business demands, then multiple power supply availabilities are provided, but the cost and complexity increase significantly
Solution Approach 1:
Multiple power supply sub-systems with different availability configurations are merged into a unified power supply system. This allows shared infrastructure resources (such as power distribution units, monitoring systems, and physical space) to serve multiple business units simultaneously, reducing overall deployment costs while still providing differentiated availability levels.
Solution Approach 2:
The power supply system adopts a universal architecture that can be configured to provide different availability levels (2N, N+1, N, etc.) for different business units. This multi-functional design eliminates the need to build separate dedicated power supply systems for each business demand, significantly reducing deployment costs while maintaining the ability to meet diverse availability requirements.
3Adaptability or versatility
If traditional power supply systems are designed, then they provide fixed availability levels, but they lack flexibility to adjust according to varying business needs
Solution Approach 1:
The power supply system implements dynamic configuration capabilities where the availability level and connection relationships between sub-systems can be adjusted according to different business demands. The system can dynamically allocate power supply resources and reconfigure connection topologies without requiring physical reinstallation, enabling flexible adaptation to varying business needs while maintaining a relatively simple underlying infrastructure.
Data Source
AI summary
The disclosure discloses a power supply system and a power supply method. The power supply system includes a first sub-system including at least two first power supply devices and a first load, the first power supply devices for powering the first load; a second sub-system including a second power supply device and a second load, the second power supply device for powering the second load; and a connection unit configured to control electrical connection or electrical disconnection between the first power supply devices and the second load; wherein power supply availability of the first sub-system is higher than power supply availability of the second sub-system. The disclosure provides more power supply availabilities through few types of power supply structures, which facilitates application scenarios such as data center to flexibly adjust the power supply structures according to business, and save cost.
