Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control elements are arranged in three phases of the Scott connected transformer on the primary side, then voltage or current control is possible, but individual control of output voltages in two single-phase circuits is not possible
Solution Approach 1:
The patent divides the control function into two separate control elements: one control element for the main transformer primary coil and another control element for the teaser transformer primary coil. This segmentation allows independent control of each single-phase circuit's output voltage while maintaining the three-phase input structure, resolving the contradiction between control capability and configuration complexity.
2Ease of operation
If control elements are arranged in two single-phase circuits, then individual control of output voltages is possible, but the configuration becomes complex requiring three sets of transformers
Solution Approach 1:
The patent merges the functions of the Scott connected transformer with two single-phase transformers into a single integrated Scott connected transformer structure. By placing control elements directly in the primary circuits of the main and teaser windings, it achieves individual output voltage control without requiring separate single-phase transformer sets, thus reducing overall device complexity while maintaining control capability.
