Power Manager Feedback Control for Cable Current Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power management systems often exceed current capacity limitations, leading to potential failures and non-compliance with regulatory standards, as they lack effective mechanisms to manage current draw through power cables efficiently.
Innovation Solution
A data processing system with a power manager and hardware resources manager that estimate and regulate input current, throttle hardware resources, and enforce power budgets to prevent excessive current draw, using multiple independent mechanisms to ensure compliance with current capacity limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power management systems operate hardware resources at full capacity, then productivity is improved, but current draw exceeds cable capacity limitations causing potential failures and non-compliance
Solution Approach 1:
The system dynamically adjusts hardware resource performance based on real-time current draw measurements. The power manager continuously monitors current consumption and dynamically throttles or scales hardware resources to maintain operation within cable capacity limits while maximizing productivity when possible.
Solution Approach 2:
The system implements a feedback mechanism where the power manager receives current draw data from monitoring components, compares it against cable capacity thresholds, and adjusts hardware resource allocation accordingly. This closed-loop control ensures compliance while optimizing performance.
2Reliability
If multiple independent mechanisms are implemented for current management, then reliability is improved through compliance assurance, but device complexity increases
Solution Approach 1:
The patent combines multiple power management functions (monitoring, estimation, throttling, and compliance checking) into a single integrated power manager component. This consolidation reduces system complexity while maintaining the reliability benefits of multiple independent mechanisms through unified control logic.

AI summary
Methods and systems for power management are disclosed. The disclosed power management may facilitate the use of different components that may have different electrical current capacity limitations. The current capacity limitations may be based on, for example, physical limitations of the components, regulatory limitations, organizational limitations, and/or other considerations. It may not be desirable to exceed the current capacity limitations. By implementing the disclosed power management methods, systems, and/or devices, operation of devices may be less likely to result in the current drawn through devices such as power cables exceeding the current capacity limitations even while other devices operably connected to the cables do not have such current capacity limitations.
