Solution Overview

Problem

Conventional information handling systems (IHS) face inefficiencies due to oversized power systems designed to handle peak power excursions, leading to costly and inefficient setups, as they often shut down due to high peak demands even when average power usage is below shutdown thresholds, resulting in data loss and unnecessary resource allocation.

Innovation Solution

A power system with a power system connector, output sensor, and controller that dynamically adjusts output to store energy in capacitance during power excursions, allowing for increased power storage and efficient use during peak demands without exceeding the power system's capability, thereby preventing shutdowns and optimizing system sizing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the power system is sized to handle peak power excursions, then the system can prevent shutdowns during high power demands, but the power system becomes oversized and inefficient for average operation

Engineering Contradiction:
Improvepower system stabilityVSAvoidpower system efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The power system proactively stores energy in the capacitance during periods when power demand is below the shutdown threshold, before peak excursions occur. This preliminary energy accumulation ensures that when high power demands arise, the stored energy can be rapidly deployed to prevent shutdowns, resolving the contradiction between reliability and efficiency by preparing in advance rather than reacting to peaks

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically changes the operational parameters of the power conversion device, adjusting the power system output based on real-time conditions. By monitoring power excursions and modifying the output parameter dynamically, the system can operate efficiently at average loads while still providing sufficient power during peak excursions, thus maintaining both reliability and efficiency

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the power system output is increased to meet peak demands, then shutdowns are prevented, but the system operates inefficiently during average power usage

Engineering Contradiction:
Improvecontinuous operationVSAvoidpower system efficiency
Core Design Contradiction:

Solution Approach 1:

The power conversion device operates in periodic cycles, alternating between storing energy in the capacitance during low-demand periods and delivering stored energy during high-demand periods. This periodic operation allows the system to maintain high efficiency during average usage while ensuring continuous operation during peaks, resolving the contradiction between continuous operation and efficiency

Inventive Principle:
Principle #19Periodic action

3Reliability

If a capacitance is added to store energy, then power excursions can be handled, but the device complexity increases

Engineering Contradiction:

Solution Approach 1:

The capacitance component serves multiple functions within the power system: it stores energy for peak excursions, filters power fluctuations, and provides voltage stabilization. By making the capacitance multi-functional, the patent reduces overall system complexity compared to adding separate dedicated components for each function, thus resolving the contradiction between reliability and device complexity

AI summary

A power system is coupled to a powered system and a system capacitance. The power system includes a power system output sensor, a power conversion device, and a power system output controller. The power system output controller includes a powered system threshold that is related to a power excursion capability of the powered system. The power system output controller is operable, in response to receiving a power system output signal from the power system output sensor that exceeds the powered system threshold, to control the power conversion device to increase the power system output from the power conversion device in order to increase the energy stored in the system capacitance for use by the powered system during a power excursion. The powered system may include processors that draw power from the system capacitance during power excursions so as to not exceed the limits of the power system.
