TLDR
In this article, a high-voltage transformer is divided into a primary side which is provided on the static gantry section and to which the output of a frequency converting circuit is supplied and a secondary-side which generates a high voltage.Abstract:
An X-ray computer tomography apparatus comprises a high-voltage transformer which performs the increase and noncontacting transmission of the power simultaneously and outputs a desired high voltage for causing X rays to be generated at the rotatable gantry section. The high-voltage transformer is divided into a primary-side which is provided on the static gantry section and to which the output of a frequency converting circuit is supplied and a secondary-side which generates a high voltage. A capacitor is connected to a secondary coil of the high-voltage transformer, thereby forming a resonance circuit.read more
