Multi-Output Power Supply Dynamic Allocation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power supply devices with multiple outputs suffer from poor power converting efficiency and user inconvenience, as they can only provide half of the total output power simultaneously to each port, leading to idle power capability and inefficient power allocation.
Innovation Solution
A power supply device with a power converting module and switching modules that allow for flexible allocation of power between output ports, enabling either one or both power output ends to supply power to either port, optimizing power utilization by adjusting based on demand and rated power values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the conventional power supply device connects both power output ends to a single output port to provide high power, then the output power for that port is sufficient, but the other output port does not provide power, resulting in idle power capability
Solution Approach 1:
The patent implements dynamic switching between different connection configurations using switching modules. The system can dynamically adjust which power output end connects to which output port based on real-time power demands, transforming the static connection into a dynamic one that adapts to varying load requirements, thereby eliminating idle power capability.
Solution Approach 2:
The patent changes the connection parameters (which power output end connects to which output port) based on power demand conditions. By monitoring power demands and adjusting connection configurations accordingly, the system optimizes power allocation to match actual needs, preventing both power deficiency and idle power capability.
2Ease of operation
If the conventional power supply device allocates power to each output port independently, then each port can provide power simultaneously, but each port is limited to half of the total output power, causing user inconvenience when higher power is needed
Solution Approach 1:
The patent makes each power output end capable of serving multiple output ports through switching modules. Each power output end can be connected to either output port or both simultaneously based on demand, providing universal functionality that adapts to different power requirements, thereby eliminating the half-power limitation while maintaining user convenience.
Solution Approach 2:
The patent segments the power allocation control into independent switching modules for each power output end. This segmentation allows flexible and independent control of each power output end's connection configuration, enabling precise power allocation that matches user needs without being constrained by fixed half-power limits.
3Adaptability or versatility
If the conventional power supply device uses fixed connection configuration, then the structure is simple, but the power allocation is inflexible and cannot adapt to varying power demands
Solution Approach 1:
The patent introduces dynamic switching modules that enable flexible power allocation adaptation to varying power demands. Although this increases device complexity, the dynamic capability allows the system to optimize power distribution in real-time, achieving high adaptability that justifies the added complexity.
Solution Approach 2:
The patent implements control modules that automatically detect power demands and autonomously adjust connection configurations without user intervention. This self-service capability manages the switching module complexity by automating the adaptation process, allowing the system to achieve high power allocation flexibility while minimizing user burden.

AI summary
The power supply device with multiple outputs includes two output ports, a power converting module with two power output ends, and two switching modules connected among the two power output ends and the two output ports. The output power from the two power output ends can be independently allocated to either one or two of the two second output ports. When one of the output ports requests for a demand power, the power supply device is able to determine which one or both of the power output ends to output power to the output port, reaching a better power allocation efficiency.
