Solution Overview
Problem
Existing power supply designs for high-power IT devices, such as AI servers, face inefficiencies and environmental challenges due to redundant power supplies, leading to increased energy consumption and electronic waste, while asymmetric designs complicate power management and reliability.
Innovation Solution
A system integrating automatic transfer switching (ATS) units with power supply units (PSUs) and air-based cooling, allowing for efficient power distribution and redundancy without the need for external ATS boxes, using dual input rectifiers and DC switches to manage power sources within the PSU form factor, ensuring reliable and efficient power delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If symmetric power supply design is used, then reliability is improved, but energy consumption increases and electronic waste increases
Solution Approach 1:
The patent applies asymmetric power supply design (N+1 configuration) where one power supply unit serves as a hot backup and remains permanently connected, while other units can be disconnected. This asymmetric approach provides reliability through redundancy while reducing energy consumption by allowing inactive power supplies to be turned off, resolving the contradiction between reliability and energy loss.
Solution Approach 2:
The patent implements dynamic power management where power supply units can be selectively connected or disconnected based on operational needs. The system dynamically adjusts the number of active power supplies from the full symmetric configuration to a reduced asymmetric configuration, optimizing both reliability and energy consumption according to actual device requirements.
2Reliability
If symmetric power supply design is used, then reliability is improved, but electronic waste increases
Solution Approach 1:
The patent transitions from symmetric to asymmetric power supply configurations, where the redundant power supply unit is permanently connected and integrated into the device architecture. This eliminates the need to dispose of unused power supply units upon device retirement, thereby reducing electronic waste while maintaining reliability through the permanently connected backup unit.
Solution Approach 2:
The patent changes the end-of-life strategy from discarding redundant power supply units to recovering and retaining them as permanent components. The asymmetric design ensures that at least one power supply unit remains permanently connected and functional, eliminating waste generation during device retirement while preserving reliability.
3Loss of energy
If asymmetric power supply design is used, then energy efficiency is improved, but power management complexity increases
Solution Approach 1:
The patent implements self-service power management where the power supply units automatically detect and respond to failures without requiring complex external control systems. The permanently connected backup unit automatically takes over when a failure occurs, simplifying power management complexity while maintaining energy efficiency through asymmetric configuration.
Solution Approach 2:
The patent introduces an intermediary control mechanism that manages the asymmetric power supply configuration. This intermediary component coordinates the connection and disconnection of power supply units, simplifying the overall power management complexity while enabling energy-efficient asymmetric operation.
4Reliability
If external ATS boxes are used, then power switching reliability is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent merges the automatic transfer switching functionality directly into the power supply units, eliminating the need for separate external ATS boxes. This integration combines the power supply and switching functions into a single unified system, reducing overall device complexity and space requirements while maintaining power switching reliability through the integrated design.
Solution Approach 2:
The patent designs power supply units with multi-functionality, incorporating both power conversion and automatic transfer switching capabilities within each unit. This universal design allows the power supply units to perform multiple functions independently, eliminating the need for separate ATS equipment and reducing system complexity while preserving reliability.
