Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The power efficiency of a base station's power system is suboptimal due to independent efficiency adjustments of the primary and secondary power supplies, resulting in reduced overall efficiency when both are optimized for maximum performance.
Innovation Solution
The first power supply sets its output voltage to various values to determine the corresponding voltage that maximizes power efficiency, allowing the power system to operate at high efficiency by adjusting based on parameters from both power supplies through communication connections like power line communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the efficiency of the primary power supply and the efficiency of the secondary power supply are both adjusted to be the highest independently, then the individual efficiency of each power supply is maximized, but the overall power efficiency of the power system is reduced
Solution Approach 1:
The patent merges the independent efficiency control of primary and secondary power supplies into a unified joint efficiency optimization system. The management module coordinates both power supplies to work together, considering their combined efficiency rather than optimizing them separately, thereby resolving the contradiction between individual component optimization and overall system performance.
Solution Approach 2:
The patent implements a feedback mechanism where the management module continuously monitors the operating states of both power supplies and adjusts their efficiency parameters based on real-time system conditions. This closed-loop control enables dynamic optimization of overall power efficiency while accounting for the interdependent nature of the primary and secondary power supplies.
2Loss of energy
If joint efficiency optimization is implemented for the power system, then the overall power efficiency is improved, but the control complexity increases
Solution Approach 1:
The patent introduces a management module as an intermediary that handles the complex coordination between primary and secondary power supplies. This intermediary component centralizes the joint efficiency optimization logic, simplifying the control architecture while achieving improved overall power efficiency through coordinated operation of both power supplies.
3Loss of energy
If the output voltage of the first power supply is fixed, then the system operation is simple, but the power efficiency cannot be optimized
Solution Approach 1:
The patent transforms the static fixed voltage operation into a dynamic voltage adjustment system. The first power supply's output voltage is made variable and can be dynamically adjusted based on system conditions to optimize power efficiency, while the management module coordinates this adjustment with the second power supply's operation to maintain overall system performance.
