Regulator Circuit With Energy Storage for Peak Power Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional approaches to provisioning power for electronic devices often result in inefficiencies, lower performance, and unreliable operation due to handling peak demand loads, unregulated input rail power, and the inability to increase power availability effectively.
Innovation Solution
The use of deterministic energy provisioning systems that predict energy requirements based on power schedules and operating states, allowing for the storage of excess energy during periods of low demand and its utilization during peak demand periods, thereby ensuring reliable and efficient power delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional approaches consistently over-provision power to handle peak demands, then reliability of device operation is improved, but efficiency deteriorates due to wasted power capacity
Solution Approach 1:
The system performs preliminary actions by storing energy in advance during periods when power demand is low. Energy storage devices are charged when available power exceeds immediate requirements, preparing energy reserves before peak demand occurs. This eliminates the need to continuously over-provision power while ensuring reliability during high-demand periods.
Solution Approach 2:
Energy storage devices act as intermediaries between the power source and the load. These intermediaries buffer the mismatch between available power and demand by absorbing excess energy when supply exceeds demand and releasing energy when demand exceeds supply, thereby resolving the contradiction between reliability and energy efficiency.
2Power
If devices slow down operation to remove causes of peak demands, then power provisioning becomes manageable, but productivity deteriorates
Solution Approach 1:
Energy storage devices serve as intermediaries that decouple the relationship between power demand and operation speed. By providing energy buffers, these intermediaries allow devices to maintain high operation speeds during peak demand without causing power provisioning problems, as the storage devices absorb the transient power excesses.
Solution Approach 2:
The system performs preliminary energy storage actions during low-demand periods, preparing energy reserves that enable high-speed operation during peak periods. This preliminary preparation allows the device to maintain productivity while managing power demands effectively.
3Object-affected harmful factors
If circuit breakers or fuses are employed to shut down devices in response to peaks, then power specifications are protected, but reliability deteriorates due to operational interruptions
Solution Approach 1:
The system applies beforehand cushioning by using energy storage devices to absorb and buffer power fluctuations before they can cause harmful effects. The storage devices cushion the impact of peak demands, preventing circuit breakers or fuses from activating and thus maintaining operational continuity while still protecting power specifications.
Solution Approach 2:
Energy storage devices act as intermediaries between the power source and the device, buffering power fluctuations and preventing harmful peaks from reaching the device. This intermediary protection eliminates the need for disruptive circuit breakers or fuses while maintaining both power specification protection and operational reliability.
4Reliability
If temporary stored power is used to provide backup power when mains power is unavailable, then reliability is improved for power outages, but the magnitude of power available for peak demands is not increased
Solution Approach 1:
The energy storage system is designed with multi-functionality, serving both as a backup power source during mains failures and as a peak demand management tool. By optimizing the storage capacity and control strategy, the same energy storage devices can provide sufficient power magnitude for peak demands while also ensuring reliability during power outages.
