Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication power supply systems often suffer from inefficiencies due to mismatched power supply currents, leading to wasted capital investment and increased operational costs, as they typically consist of rectifiers at the same power level, failing to adapt to diverse power requirements across different application scenarios.
Innovation Solution
A method and device for a mixed insertion system of rectifiers with different power levels, which involves acquiring input information, determining power-on/power-off control modes, and performing power-on/power-off rotations based on phase currents and powered-on times to optimize energy usage and reduce no-load losses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If rectifiers at the same power level are used in parallel, then the power supply system is simple to manage, but the mismatch between power supply current and load requirement causes energy waste and increased operational costs
Solution Approach 1:
The patent segments the rectifier population into different power levels (e.g., 500W, 1000W, 2000W) rather than using uniform rectifiers. This segmentation allows the system to match power supply more precisely to load requirements, reducing energy waste from oversized rectifiers operating at low load factors.
Solution Approach 2:
The patent applies local quality by assigning different power levels to different rectifiers based on specific slot configurations and load requirements. Each rectifier slot is optimized for its specific power level, allowing the system to adapt locally to varying power demands across different application scenarios.
2Adaptability or versatility
If rectifiers at different power levels are mixed and inserted in parallel, then adaptability to diverse power requirements is improved, but the system complexity increases
Solution Approach 1:
The patent implements dynamic rectifier selection and control based on real-time load conditions. The system dynamically determines which rectifiers to power on/off and at what power levels, adapting to changing power requirements without requiring manual reconfiguration. This dynamic approach manages complexity through automated control algorithms.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system continuously monitors load conditions and adjusts rectifier operation accordingly. The control system receives feedback on power demand and automatically optimizes the mix of active rectifiers at different power levels, managing system complexity through closed-loop control.
3Reliability
If continuous operation of rectifiers is maintained, then system reliability is ensured, but no-load losses increase
Solution Approach 1:
The patent implements periodic operation of rectifiers through rotation mechanisms. Instead of continuous operation, rectifiers are cycled on and off in a rotational fashion, allowing them to rest periodically. This reduces no-load losses while maintaining system reliability through redundancy and scheduled operation of multiple rectifiers.
Solution Approach 2:
The patent applies discarding and recovering by temporarily taking rectifiers offline (discarding their service) to reduce no-load losses, then bringing them back online (recovering their service) when needed. The rotation mechanism ensures that rectifiers are cycled between active and standby states, recovering their utility while minimizing energy waste during idle periods.
4Duration of action of stationary object
If rectifiers operate for extended periods without rotation, then operational stability is maintained, but service life is reduced due to wear
Solution Approach 1:
The patent implements periodic rotation of rectifiers between active and standby states. This regular cycling prevents any single rectifier from operating continuously for extended periods, distributing wear more evenly across the rectifier population and extending overall service life while maintaining operational stability through redundancy.
Solution Approach 2:
The patent ensures continuity of useful action through the rotation mechanism. While individual rectifiers are cycled on and off, the system as a whole maintains continuous power supply capability. The rotation ensures that always sufficient rectifiers remain active to meet load demands, maintaining operational continuity while managing component wear.
