Comparison of energy storage devices for diagnostic X-Ray Generator

High voltage power is needed by diverse application fields such as high precision medical equipment, and development of an X-ray generator equipped with large capacity power is accordingly required. Commercial AC power based X-ray generator has a disadvantage of having limitation in the location and of being sensitive to the power characteristics, the necessity for an independent power type X-ray generator is increasing recently. For this reason, development of an energy storage device based stand-alone type X-ray generator is required. This paper compared characteristics of energy storage devices, and composed equivalent models of each energy storage devices, and analyzed characteristics of available energy as a function of output voltage and power. An energy storage device based 32 [kW] class X-ray generator was constructed, and the output characteristics of diagnostic X-ray generators with each energy storage devices were compared through simulations and experiments.
