Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power conversion systems lack flexibility and efficiency in configuring power devices between different modes, such as upside-up and upside-down configurations, which limits their ability to maintain voltage within thresholds and adapt to varying power sources and loads.
Innovation Solution
The system employs a plurality of power devices configured in either upside-up or upside-down configurations, allowing for switching between modes based on signals and parameters to maintain voltage thresholds and ensure efficient power conversion, with connectors arranging these devices in series or parallel to optimize power distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power devices are configured in fixed modes (upside-up or upside-down), then the system structure is simple and easy to manufacture, but the system lacks flexibility and cannot adapt to varying power sources and loads
Solution Approach 1:
The power conversion system implements dynamic configuration by enabling power devices to switch between upside-up and upside-down modes based on real-time operating conditions. The controller dynamically adjusts the configuration of power devices in response to varying power sources and loads, transforming a static system into an adaptive one that optimizes performance for different scenarios.
Solution Approach 2:
The patent creates a universal power conversion system where power devices can perform multiple functions by switching between different configurations. The same power device can operate in upside-up mode for certain operating conditions and upside-down mode for others, eliminating the need for separate dedicated devices for different configurations and enhancing system versatility.
2Adaptability or versatility
If power devices switch between different configurations, then the system flexibility and adaptability improve, but the control complexity and difficulty of operation increase
Solution Approach 1:
The controller monitors operating parameters such as input voltage, output voltage, and load conditions, and uses this feedback to automatically determine the optimal configuration mode for power devices. This closed-loop control eliminates the need for manual intervention in mode switching, simplifying operation while maintaining high adaptability to varying conditions.
Solution Approach 2:
The power conversion system performs self-configuration by automatically selecting appropriate operating modes for power devices based on real-time conditions. The controller autonomously manages the switching between upside-up and upside-down configurations without requiring external control or manual adjustment, making the system easy to operate despite its complexity.
3Productivity
If connectors arrange power devices in specific series or parallel configurations, then power distribution is optimized, but the system loses flexibility in adapting to different operating conditions
Solution Approach 1:
The system implements dynamic reconfiguration of power device connections, allowing connectors to switch between series and parallel arrangements based on operating conditions. This dynamic connection management enables the system to optimize power distribution efficiency for each specific scenario while maintaining adaptability to varying power sources and loads.
