Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing power delivery from auxiliary power supplies in systems like LED lighting are inefficient, often leading to overpowering or underpowering loads, and are complex to implement, potentially damaging hardware.
Innovation Solution
A system with a controller that enables or disables auxiliary power supplies based on voltage sensing at the output, using a timeout period defined by a random number to ensure appropriate power delivery to loads, preventing multiple supplies from overpowering the load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple auxiliary power supplies are connected in parallel to provide sufficient power, then the total power capacity increases, but the load may receive excessive power causing damage or overheating
Solution Approach 1:
The controller continuously monitors the voltage at the output of the auxiliary power supply and uses this feedback to dynamically adjust the enable/disable state. When voltage is detected (indicating another power supply is active), the controller disables the current power supply to prevent overpowering. When no voltage is detected, the power supply is enabled to provide power to the load.
2Ease of manufacture
If manual configuration methods are used to enable or disable auxiliary power supplies, then manufacturing processes become complex and time-consuming, but automated sensing and control adds hardware complexity
Solution Approach 1:
The auxiliary power supply system performs self-configuration through automated voltage sensing and controller logic. Each power supply unit independently monitors its own output voltage and automatically adjusts its enable state based on the presence of voltage, eliminating the need for manual configuration during manufacturing while maintaining simple hardware architecture.
3Manufacturing precision
If automated voltage sensing control is implemented, then power delivery accuracy improves, but response time may be delayed due to sensing and processing delays
Solution Approach 1:
The controller is pre-configured with the logic to enable the auxiliary power supply when no voltage is sensed and disable it when voltage is sensed. This preliminary setup of control logic allows the system to respond immediately to voltage changes without requiring complex real-time decision algorithms, reducing processing delays while maintaining accurate power delivery control.

AI summary
There are provided systems, apparatuses, and methods for controlling power delivery from an auxiliary power supply. For example, there is provided a method that includes generating a first random number to define a timeout period. During the timeout period, the method may detect whether a voltage is present at an output of an auxiliary power supply, may disable the auxiliary power supply when the voltage is detected at the output, and may enable the auxiliary power supply when the voltage is not detected at the output.
