Adaptive Power Supply Protection for Fast Voltage Transients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems in computing systems, particularly for AI processors, struggle to handle unpredictable and excessive transient power demands due to uncharacterized algorithms, leading to potential system shutdowns, overcurrent, or thermal issues.
Innovation Solution
Implementing a system with a transient sensor and power control processing entity that senses voltage transients at a higher rate than the power supply, allowing for adaptive power load adjustments, such as frequency scaling and power distribution, to maintain stable voltage levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the transient sensor operates at a higher sensing rate than the power supply, then voltage transients can be detected and responded to more quickly, but the system complexity and cost increase
Solution Approach 1:
The patent introduces a transient sensor as an intermediary component that specifically monitors voltage transients at a higher rate than the main power supply control loop. This mediator captures fast transient information that would otherwise be missed, enabling the power control processing entity to respond appropriately without requiring the entire power supply system to operate at the higher transient rate, thus resolving the contradiction between transient sensing speed and overall system complexity
Solution Approach 2:
The patent segments the power supply control function into two distinct parts: the main power supply control loop that operates at a standard rate, and the transient sensing function that operates at a higher rate. This segmentation allows each part to be optimized independently - the transient sensor captures fast changes while the main control loop maintains stable operation, avoiding the need to increase the complexity of the entire system
2Stability of the object's composition
If the power control processing entity dynamically adjusts power load based on sensed transients, then voltage stability is improved, but the response time and control complexity increase
Solution Approach 1:
The patent implements preliminary action by having the transient sensor continuously monitor voltage conditions and prepare transient detection data before actual transients occur. The power control processing entity maintains a ready state with pre-configured response strategies, so when a transient is detected, the system can immediately execute the appropriate power load adjustment without delay for analysis or decision-making, thus improving both voltage stability and response time
Solution Approach 2:
The patent establishes a feedback loop where the transient sensor continuously monitors voltage conditions and feeds this information to the power control processing entity, which then adjusts the power load accordingly. This closed-loop feedback mechanism ensures that voltage stability is maintained by continuously comparing actual voltage conditions with desired conditions and making real-time adjustments, while the feedback is optimized to provide rapid response through direct coupling between the transient sensor and power control entity

AI summary
Methods, systems, and apparatuses for adaptive power supply voltage transient protection are disclosed. One system includes a power supply, a transient sensor, and a power control processing entity. The power supply operates to provide power to one or more processors. The transient sensor is connected to the power supply and operates to sense transients on the power supply at greater than a predetermined speed or rate. The power control processing entity operates to receive a representation of the sensed transients and adjust a power load based on the sensed transients.
