Parallel UPS Power Distribution via Passive Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional uninterrupted power supply systems require expensive active components that are not linearly scalable and incur downtime during failures, leading to inefficiencies and higher costs due to the need for synchronization of power sources.
Innovation Solution
A power backup system comprising multiple uninterruptible power supplies (UPS) connected in parallel to independent power sources without active components, ensuring uninterrupted power delivery even if one source fails, through direct connections and passive components like circuit breakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active components (active switches) are used in conventional UPS systems, then power distribution control is achieved, but system cost increases, scalability is limited, and downtime occurs during component failures
Solution Approach 1:
The patent removes active switching components from the power distribution path between independent power sources and UPS inputs. By extracting these problematic active components, the system achieves passive direct connection of multiple power sources to multiple UPS units, eliminating the reliability issues and costs associated with active switches while maintaining power distribution control through the inherent characteristics of the passive connection architecture
Solution Approach 2:
The system segments the power distribution architecture into independent parallel paths, where each UPS unit connects directly to independent power sources without shared active components. This segmentation allows each UPS to operate autonomously, improving overall system reliability while enabling linear scalability by simply adding more UPS units and power sources without complex coordination requirements
2Reliability
If active components are used for power synchronization, then synchronized power supply to loads is achieved, but system cost and energy losses increase
Solution Approach 1:
The patent replaces active electronic switching mechanisms with passive electrical connections. By substituting active components that consume energy and generate losses with passive direct connections, the system achieves power synchronization through the natural electrical characteristics of parallel connections, eliminating the energy losses associated with active switching while maintaining synchronized power supply to loads
3Adaptability or versatility
If active components are predetermined for each UPS system, then individual system control is achieved, but scalability to additional loads is limited
Solution Approach 1:
The patent creates a universal passive connection architecture that can accommodate any number of UPS units and power sources. By using standardized passive connections rather than predetermined active components configured for each individual UPS, the system achieves linear scalability where additional UPS units and power sources can be added to the parallel architecture without requiring complex reconfiguration or additional active control components
