1. A voltage generating apparatus comprising:
a voltage generating apparatus that generates a pulse signal according to an X-ray irradiation signal and generates a predetermined voltage according to the pulse signal; and
an X-ray tube that generates X-rays according to the voltage from the voltage generating apparatus,
wherein the voltage generating apparatus comprises an arc detecting unit that detects arc discharge by detecting a current of the X-ray tube,
wherein the voltage generating apparatus comprises:
a console that receives the X-ray irradiation signal to generate a control signal,
a pulse control unit that receives the control signal from the console to generate a pulse signal, and
a high voltage generating unit that receives the pulse signal from the pulse control unit to generate a high voltage, and detects the current of the X-ray tube to detect arc discharge,
wherein the console comprises a first control unit that receives the X-ray irradiation signal to generate a first control signal and a second control signal,
wherein the pulse control unit comprises:
a second control unit that receives the first control signal and second control signal from the console to generate a third control signal and a fourth control signal,
a converter that converts the third control signal, and
a pulse generating unit that receives the fourth control signal and an output signal from the converter to generate a pulse signal,
wherein the high voltage generating unit includes an arc detecting unit that detects arc discharge from the current of the X-ray tube,
wherein the high voltage generating unit further comprises:
a transformer that generates a high voltage to be applied to the X-ray tube according to the pulse signal from the pulse control unit,
a high voltage switch that controls application of the high voltage generated from the transformer to the X-ray tube,
a voltage detecting unit that detects a high voltage applied to the X-ray tube and feeds the high voltage back to the pulse generating unit, and
a current detecting unit that detects the current of the X-ray tube,
wherein the arc detecting unit detects arc discharge from the output of the current detecting unit,
wherein the current detecting unit includes a first comparator that compares a reference value with the current of the X-ray tube, and
wherein the arc detecting unit includes a second comparator that compares the reference value and the output of the current detecting unit.
