Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-winding transformer is used to achieve adjustable multi-level voltages, then voltage adjustment capability is provided, but the system becomes bulky, heavy, and occupies significant space
Solution Approach 1:
The patent replaces the traditional oil-immersed multi-winding transformer with a solid state transformer (SST) that uses power electronic components (IGBTs, capacitors, inductors) to achieve voltage transformation and adjustment. This substitution of mechanical/electromagnetic system with an electronic system reduces volume, weight, and eliminates oil immersion requirements while maintaining multi-level voltage output capability for electrolysis cells.
Solution Approach 2:
The SST dynamically adjusts output voltage parameters through electronic control of switching devices (IGBTs) and modulation techniques, enabling flexible multi-level voltage output without physical transformer tap changes. This allows precise voltage matching for different electrolysis cell specifications while reducing the physical size of the transformation system.
2Power
If a multi-winding transformer is used, then voltage transformation is achieved, but installation difficulty increases significantly
Solution Approach 1:
The solid state transformer replaces the bulky oil-immersed transformer with a compact electronic power conversion system using modular components (IGBT modules, capacitors, inductors). This reduces installation complexity, eliminates the need for oil handling and special installation precautions, and allows easier integration into existing electrolysis systems while maintaining full voltage transformation capability.
3Adaptability or versatility
If the number of secondary output windings is increased to accommodate expansion, then more electrolysis devices can be powered, but the transformer becomes more complex and costly
Solution Approach 1:
The solid state transformer uses a single output configuration with electronic switching (IGBTs) that can dynamically allocate power to multiple electrolysis cells with different voltage requirements. This universal electronic control approach replaces multiple dedicated output windings, simplifying the transformer structure while enabling flexible expansion to accommodate any number of electrolysis devices through software/control logic rather than physical rewiring.
