Solution Overview
Problem
Existing power supply circuits, such as the Cockcroft-Walton circuit, are limited to generating a single DC voltage, making it difficult to provide multiple DC voltages required by small modularized electronic circuits, and configurations using multiple transformers and rectifiers result in complexity, size, and cost issues.
Innovation Solution
A power supply circuit incorporating one or more Cockcroft-Walton circuits with multiple output terminals, supplied with AC voltage, outputs different DC potentials by varying the AC voltage magnitude, allowing for simple generation of multiple DC voltages through a combination of positive and negative potentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple transformers and rectifier circuits are used to generate multiple DC voltages, then multiple DC voltages can be supplied, but the configuration becomes complicated and size increases
Solution Approach 1:
The patent merges multiple voltage generation functions into a single Cockcroft-Walton circuit by providing multiple output terminals that tap into different stages of the voltage multiplication process. This allows one circuit to perform what would traditionally require multiple separate circuits, thereby reducing configuration complexity while maintaining the ability to supply multiple DC voltages.
Solution Approach 2:
The Cockcroft-Walton circuit is designed with multi-functionality by incorporating multiple output terminals that can deliver different DC voltage levels simultaneously. Each output terminal corresponds to a different stage in the voltage multiplication sequence, enabling the single circuit to serve multiple voltage requirements of electronic devices without needing separate dedicated circuits for each voltage level.

3Device complexity
If a single Cockcroft-Walton circuit is used, then the configuration is simple, but only one DC voltage can be obtained
Solution Approach 1:
The patent applies segmentation by dividing the voltage multiplication process into distinct stages, with each stage having its own output terminal. This allows the single Cockcroft-Walton circuit to provide multiple DC voltage levels by tapping into different stages of the multiplication sequence, thereby maintaining configuration simplicity while achieving the ability to supply multiple voltages.
Solution Approach 2:
The patent adds a dimensional aspect to the traditional single-output Cockcroft-Walton circuit by incorporating multiple output terminals along the voltage multiplication chain. This transforms the circuit from a single-function voltage generator into a multi-output voltage distribution system, enabling it to supply multiple DC voltages simultaneously while keeping the overall configuration simple.
