摘要
An AC high-voltage device includes a voltage controlling unit (212, 215, 216) that controls an AC transforming unit (211). The AC transforming unit (211) transforms supplied power to an AC high voltage. The voltage controlling unit (212, 215, 216) includes a constant-voltage controlling unit (212, 215, 216) and an turn-off unit (212, 215). The constant-voltage controlling unit (212, 215, 216) controls the AC transforming unit (211) when an over-current does not occur in the AC high voltage. The turn-off unit (212, 215) turns off the AC transforming unit (211) during a period in which an over-correct occurs. The constant-voltage controlling unit (212, 215, 216) re-starts the AC transforming unit (211) after the period.
