Abstract
According to one embodiment, an X-ray high voltage apparatus includes an AC/DC converter, an inverter circuit, a high voltage generator, a power storage device, and the DC/DC converter. The AC/DC converter converts an AC voltage into a DC voltage. The inverter circuit converts the DC voltage into an AC voltage. The high voltage generator externally outputs a power obtained by boosting and rectifying the AC voltage outputted by the inverter circuit. The DC/DC converter receives the DC voltage, and charges and discharges the power storage device. The DC/DC converter is a multi-phase converter including DC/DC converter blocks. Each of the DC/DC converter blocks includes a choke coil. The choke coil is provided with a correction winding for correcting a deviation of a magnetic flux caused by a DC current superimposed on the corresponding choke coil. The correction windings are applied with a summed current based on the DC/DC converter.
