ABSTRACT:
An AC high voltage detecting device includes a high voltage power supply (HVPS) to convert a low voltage into an AC high voltage, a rectifier to rectify the converted AC high voltage into a positive voltage and a negative voltage, a voltage divider to divide the rectified positive voltage and the rectified negative voltage into a first voltage and a second voltage, respectively; and a detector to read out a sum component of the first and the second voltages to detect the AC high voltage in a DC level. Since the AC high voltage supplied from the high voltage power supply is detected after being converted into a DC voltage, there is no variance caused due to various devices required to detect an AC voltage.
