Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The research and development of power electronics converters is expensive and complex due to the need for multiple setups and different converters, requiring large space and long design times, as existing systems lack flexibility and require separate components for each converter type.
Innovation Solution
An automatic reconfigurable system for power electronics converters that can be configured into AC-DC, DC-AC, or DC-DC converters using a web-based application with a graphical user interface, allowing users to select and design topologies and control algorithms remotely, and automatically reconfigure the converter's layout and components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate power converters are used for different converter types (AC-DC, DC-AC, DC-DC), then each converter can be optimized for its specific function, but the system complexity, space requirements, and cost increase significantly
Solution Approach 1:
The patent implements a single power converter system that can operate in multiple converter modes (AC-DC rectifier, DC-AC inverter, DC-DC converter) by reconfiguring the same power stage and control circuitry. The system uses a unified topology with controllable switches and energy storage elements that can be switched between different connection configurations to achieve different converter functions, eliminating the need for separate dedicated converters for each type.
Solution Approach 2:
The patent employs dynamic reconfiguration of the power converter circuit through controlled switching of semiconductor devices and repositioning of energy storage elements (inductors and capacitors). The system can dynamically change its topology and operating mode based on control signals, allowing transition between different converter types without physical reconfiguration or replacement of components.
2Adaptability or versatility
If multiple separate power converters and setups are used for research, then each converter type can be studied independently, but the research cost, space requirements, and design time increase
Solution Approach 1:
The reconfigurable power converter provides a unified platform for researching multiple converter types (AC-DC, DC-AC, DC-DC) using the same physical system. Researchers can study different converter topologies and control strategies on a single device by reconfiguring the power stage, reducing the need for multiple separate research setups and accelerating the research process.
3Reliability
If multiple separate power converters are used, then each converter can be optimized for its specific application, but the overall cost and component requirements increase
Solution Approach 1:
The patent combines the power stages, control circuits, and energy storage elements of multiple converter types into a single integrated reconfigurable system. By merging these components and enabling them to serve multiple functions through reconfiguration, the system reduces the total component quantity while maintaining the performance capabilities of individual dedicated converters.
