Modular Power Supply System for High-Power Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized electronic devices require high-power supply systems that are complex, difficult to maintain, and have poor cooling efficiency, making them unsuitable for meeting the demands of supersized display devices.
Innovation Solution
A power supply system comprising at least two independent power supplies connected in parallel, each simple in structure and easy to maintain, with a control module to manage power distribution based on the electronic device's electricity demand, allowing flexible control of power supply states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a single large-sized power supply system is used to meet high power demands, then power supply capacity is sufficient, but the structure becomes complex and difficult to maintain
Solution Approach 1:
The power supply system is divided into multiple independent small-sized power supply modules instead of using a single large power supply. Each module can operate independently, and they work in parallel to meet the total power demand. This segmentation reduces the complexity of each individual module while maintaining sufficient overall power capacity.
2Power
If multiple components are integrated into one power supply to meet high power demands, then power capacity is sufficient, but the cooling effect becomes poor
Solution Approach 1:
By dividing the power supply into multiple separate modules, each module has its own cooling space and heat dissipation path. This prevents heat accumulation that would occur in a tightly integrated single power supply, thereby improving overall cooling efficiency while maintaining sufficient power capacity.
3Power
If a single large power supply is used, then power capacity is sufficient, but maintenance and management become more difficult
Solution Approach 1:
The modular architecture allows each power supply module to be independently maintained and replaced. If one module fails, only that specific module needs to be serviced rather than the entire power supply system, significantly easing maintenance and management tasks while providing sufficient total power capacity.
4Power
If multiple transformers and rectifying filtering modules are integrated, then power capacity is sufficient, but the failure rate increases
Solution Approach 1:
By distributing the transformers and rectifying filtering modules across multiple independent power supply modules, the failure of one module does not affect the others. This modular approach reduces the overall system failure rate while maintaining sufficient power capacity through the parallel operation of healthy modules.
