Multi-Unit X-Ray Power Supply for High-Speed Serial Radiography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional X-ray equipment is unable to perform high-speed serial radiography due to the alternating discharging and charging of high-pressure condensers, which limits the ability to conduct high-speed serial radiography, especially in environments without a commercial power supply.
Innovation Solution
The X-ray equipment is configured with multiple pressure rising units and a switching control unit that switches between these units to manage the discharging and charging of condensers, allowing for continuous high-speed serial radiography by ensuring that at least one charged unit is always available for X-ray generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single high pressure condenser is used for X-ray generation, then the device structure is simple, but high-speed serial radiography cannot be performed because the condenser must alternate between charging and discharging
Solution Approach 1:
The single high voltage generating device is divided into multiple independent high voltage generating units (first unit with first condenser, second unit with second condenser). Each unit can operate independently, allowing one unit to discharge while another charges, thereby enabling continuous high-speed serial radiography without waiting for condenser recharging.
2Productivity
If the high pressure condenser is discharged for X-ray photography, then X-ray images can be obtained, but the condenser must be recharged before the next radiography, causing interruption in serial radiography
Solution Approach 1:
By providing multiple high voltage generating units with separate condensers, the system ensures continuous useful action. While one condenser is discharging to produce X-rays, another condenser is simultaneously charging, eliminating idle time and enabling uninterrupted serial radiography.
Solution Approach 2:
The condensers are charged in advance before they are needed for X-ray generation. With multiple condensers available, one can be pre-charged while another is in use, ensuring that a charged condenser is always ready for immediate discharge when radiography is required.
3Productivity
If conventional X-ray equipment is used without commercial power supply, then portability is improved, but high-speed serial radiography cannot be performed due to battery power limitations
Solution Approach 1:
The power system is segmented into multiple independent high voltage generating units, each with its own condenser that can be independently charged from the battery. This allows efficient utilization of battery power across multiple units, enabling high-speed serial radiography even in portable applications without commercial power supply.

AI summary
The X-ray equipment related to the embodiment is configured from a plurality of pressure rising units, a switching unit, and a switching control unit. The plurality of pressure rising units are connected to the battery unit and generate direct current voltage. The switching unit switches over the plurality of pressure rising units and supplies direct current voltage to the X-ray generating unit. The switching control unit transmits switching instructions to the switching unit for switching over the pressure rising unit after receiving voltage supply instructions with respect to the X-ray generating unit until said voltage supply instructions terminate. The switching control unit controls discharging of the condenser inside the pressure rising unit switched over by the switching instructions and the control of commencing charging of the condenser inside the pressure rising unit following termination of discharging.
