Dynamic Current Sharing in Redundant Power Supply Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power supply systems in computer technology lack the ability to dynamically reconfigure current sharing and fault monitoring tolerances during operation, leading to static and unchangeable settings that do not adapt to varying power requirements, potentially causing inefficiencies and reliability issues.
Innovation Solution
Implementing a master service processor that dynamically configures current sharing and fault monitoring in redundant power supply modules by summing present power requirements and setting current sharing and fault reporting tolerances, allowing for adaptive adjustments during powered operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static current sharing and fault reporting tolerances are set by the manufacturer, then the power supply system is simple to manufacture and operate, but it cannot adapt to varying power requirements during operation
Solution Approach 1:
The patent implements dynamic current sharing and fault reporting tolerances that automatically adjust during operation based on actual power requirements. The master service processor continuously monitors power consumption and recalculates tolerances in real-time, transforming static manufacturer-set values into dynamic adaptive parameters that respond to changing system conditions
Solution Approach 2:
The system changes the numerical values of current sharing and fault reporting tolerances based on measured power requirements. The master service processor calculates optimal tolerance values dynamically and updates the power supply modules, allowing the parameters to vary within safe operational limits to match actual load conditions
2Reliability
If current sharing tolerance is set to a fixed predetermined value, then fault monitoring is simple, but it may cause false faults or miss actual faults under varying load conditions
Solution Approach 1:
The system implements a feedback mechanism where the master service processor continuously monitors actual power consumption and uses this information to dynamically adjust fault reporting tolerances. The feedback loop ensures that fault detection thresholds remain appropriate for current operating conditions, preventing both false positives and missed detections
Solution Approach 2:
The master service processor proactively calculates and sets appropriate fault tolerances before faults occur by continuously monitoring power requirements. This preliminary adjustment of parameters based on predicted or current load conditions ensures that the fault monitoring system is always optimized for the current operating state
3Productivity
If redundant power supply modules operate with static current sharing settings, then the system is easier to operate, but it cannot optimize power distribution under changing system configurations
Solution Approach 1:
The power supply system performs self-optimization through the master service processor, which automatically monitors power requirements and adjusts current sharing tolerances without user intervention. The system serves itself by dynamically reconfiguring power distribution based on actual load conditions, eliminating the need for manual parameter adjustment while maximizing efficiency
