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 optimal voltage thresholds and adapt to varying power sources and loads.
Innovation Solution
A power system comprising a plurality of power devices configured in either upside-up or upside-down configurations, with the option to switch between modes based on signals and parameters, allowing for permanent or non-permanent connections, and using connectors to enforce specific arrangements, ensuring voltage control across converters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power devices are configured in fixed modes (either all upside-up or all upside-down), then the system structure is simple, but the adaptability to different power sources and loads is limited
Solution Approach 1:
The patent implements dynamic configuration by enabling power devices to switch between upside-up and upside-down modes based on real-time system conditions. The controller dynamically determines the optimal configuration for each power device, allowing the system to adapt to varying power sources and loads while maintaining manageable complexity through automated control.
Solution Approach 2:
The patent creates universal power devices that can function in multiple configuration modes (upside-up and upside-down). This multi-functionality allows a single type of power device to serve different roles in the system depending on the operational requirements, enhancing adaptability without proportionally increasing device complexity.
2Adaptability or versatility
If power devices are dynamically switched between different configuration modes, then the adaptability improves, but the control complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the controller continuously monitors system parameters and uses this information to determine the optimal configuration mode for each power device. The controller receives feedback about the operational state and adjusts the configuration accordingly, managing control complexity through intelligent decision-making based on real-time conditions.
Solution Approach 2:
The patent implements self-service control where each power device can autonomously determine its configuration mode based on system conditions and control signals. The system automatically manages the complexity of mode switching without requiring external intervention, with the controller making independent decisions about optimal configurations based on predefined criteria and real-time parameters.
3Ease of operation
If connectors enforce specific arrangements of power devices, then the voltage control is simplified, but the flexibility in configuration is reduced
Solution Approach 1:
The patent resolves this contradiction by making the connector arrangement dynamic rather than fixed. Connectors can be reconfigured to enforce different arrangements depending on the operational requirements. The system transitions from static connector assignments to dynamic reconfigurable connections, allowing voltage control simplicity to be maintained while adapting to different configuration needs.

AI summary
Systems, apparatuses, and methods are described for power conversion. The power conversion may be done by a plurality of power devices with different configurations. For example, the plurality of power devices may include one or more converters with an upside-up buck configuration and one or more converters with an upside-down buck configuration. The power conversion may be done by one or more power devices that may be configurable between different modes of configuration. For example, one or more power converters may be configured in either an upside-up buck configuration mode or an upside-down buck configuration mode. The selection of a certain mode of configuration of the converter may be permanent or non-permanent.
