A new X-ray inspection machine will use a digitally controlled, wide-bandgap high voltage generator to replace older, less efficient power supplies. X-ray inspection machines are used across manufacturing and security to check for contaminants, structural flaws, or hidden objects inside products and packages. The current high voltage generators in these machines are often bulky, inefficient, and difficult to control precisely. This project aims to develop a generator based on wide-bandgap semiconductors—materials that handle higher voltages and temperatures more efficiently than traditional silicon. The digital control system will allow for more stable and adjustable X-ray output. If successful, the new generator could make X-ray inspection machines smaller, more reliable, and more energy-efficient. This matters for industries that rely on non-destructive testing: food production lines checking for metal or glass fragments, airport baggage scanners, and quality control in electronics manufacturing. The project also includes a knowledge transfer component, embedding advanced engineering skills into the company so similar improvements can be applied across its entire product range. The research is applied and commercially focused, with no fundamental science component.
