Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If controlled switches are used in conventional voltage multipliers with alternating reference potentials, then voltage multiplication can be achieved, but the control circuit complexity increases significantly
Solution Approach 1:
The patent applies equipotentiality by connecting the reference potential of the controlled switches to ground through the switching circuit. This ensures that the control switches operate at a stable reference potential rather than alternating potentials, simplifying the control circuitry while maintaining voltage multiplication functionality.
Solution Approach 2:
The patent introduces an intermediary switching circuit that acts as a mediator between the winding blocks and ground. This switching circuit provides a reference potential connection point that simplifies the control of the controlled switches, reducing the overall control circuit complexity while enabling voltage multiplication.
2Power
If potential-free controlled switches are used to handle alternating reference potentials, then voltage multiplication is enabled, but the device complexity and control difficulty increase
Solution Approach 1:
By establishing a stable reference potential connection to ground through the switching circuit, the patent eliminates the need for potential-free controlled switches. The controlled switches can now operate with standard potential references, making them easier to control and reducing operational complexity.
3Device complexity
If a stable reference potential is provided for controlled switches, then control circuit complexity is reduced, but the voltage multiplication mechanism must be redesigned
Solution Approach 1:
The patent segments the voltage multiplier into distinct functional blocks: winding blocks, controlled switches, and a switching circuit. This segmentation allows the reference potential to be stabilized at the switching circuit level while maintaining the voltage multiplication function through the coordinated operation of segmented components.
Solution Approach 2:
The switching circuit serves as an intermediary that reconciles the stable reference potential requirement with the voltage multiplication mechanism. It mediates between the ground-referenced controlled switches and the alternating potential requirements of the winding blocks, enabling both simplified control and effective voltage multiplication.
