    Abstract: Provided are a high-voltage power supply apparatus and method for supplying high-voltage power to a digital flat panel X-ray detector to accelerate the separation of charges ionized upon the irradiation of the digital flat panel X-ray detector with X-rays. The high-voltage power supply apparatus includes a power source outputting high-voltage power; a path determiner providing a supply path for supplying the high-voltage power to the digital flat panel X-ray detector and a short-circuit path for short-circuiting the high-voltage power; and a path controller determining the supply path and the short-circuit path. Therefore, it is possible to prevent an overshoot of the waveform of the high-voltage power. In addition, it is possible to improve the uniformity of a radiation image and reduce the time taken to obtain a radiation image by quickly discharging charges when the high-voltage power is short-circuited.
