Abstract
Modern X-ray generators are required to deliver a peak power between 30 kW and 120 kW. This requirement places demanding constraints on the design of the power inverters used to supply such X-ray generators, at the same time that there exist industry incentives to reduce the size of X-ray generators. An trend towards increased frequencies of switching operation in the power stage of modern X-ray generators makes it possible to use air-core inductors, rather than magnetic-core inductors. This application discusses an air-core inductor assembly having an integral current sensor. According to this application, a current sensor can be more accurately provided, which does not drift in position over time, and in a way which reduces the overall bill of materials.
