Solution Overview
Problem
High voltage generators face challenges in designing compact and lightweight high voltage transformer apparatuses due to the complexity of insulation requirements and space occupation by multiple devices and circuit boards, which hinders miniaturization and efficiency.
Innovation Solution
The high voltage transformer apparatus features a tank with a first transformer unit for positive voltage and a second transformer unit for negative voltage disposed on the same side, separated by an insulating plate, with integrated circuit boards for rectification, filtering, and sampling, and uses insulating oil and layers to reduce size and weight while maintaining effective insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate circuit boards and devices are used for positive and negative voltage groups, then the insulation between positive and negative voltage groups can be ensured, but the volume and weight of the high voltage tank increase
Solution Approach 1:
The patent combines the rectifier circuit, filter circuit, and sampling circuit into a single integrated circuit board that handles both positive and negative voltage groups. This merging of previously separate circuit boards and devices reduces the overall volume and weight of the high voltage tank while maintaining functional separation through internal circuit design
Solution Approach 2:
The integrated circuit board performs multiple functions simultaneously - it serves as the insulating structure between positive and negative voltage groups, the mounting platform for rectifier devices, the substrate for filter circuits, and the interface for sampling circuits. This multi-functionality eliminates the need for separate dedicated components for each function
2Reliability
If multiple separate circuit boards and devices are used for positive and negative voltage groups, then the insulation between positive and negative voltage groups can be ensured, but the device complexity increases
Solution Approach 1:
The patent merges multiple separate circuit boards (rectifier circuit board, filter circuit board, sampling circuit board) into a single integrated circuit board. This reduces the number of discrete components and simplifies the overall device structure while maintaining the functional separation between positive and negative voltage groups through internal circuit architecture
Solution Approach 2:
The integrated circuit board is designed to perform multiple functions that were previously distributed across separate devices - it provides insulation between voltage groups, hosts rectifier devices, implements filter circuits, and enables sampling functions, thereby reducing device complexity
3Volume of moving object
If the distance between components and tank walls is reduced for miniaturization, then the volume decreases, but the insulation reliability may be compromised
Solution Approach 1:
The patent applies different insulation strategies to different locations within the tank. The integrated circuit board provides localized insulation between positive and negative voltage groups at the component level, allowing reduced spacing between components and tank walls while maintaining insulation reliability through the board's inherent insulating properties and circuit design
