Abstract

See full text

According to one aspect of the present invention, a high-voltage power supply device outputs a high voltage of both positive and negative polarities in a switchable manner and includes: a first voltage generation unit; a second voltage generation unit; a first discharging diode connected to the first voltage generation unit; a second discharging diode connected to a the second voltage generation; a first output circuit connected including a first switch and a protective resistor connected in series to each other; a second output circuit including a second switch and a protective resistor connected in series to each other; an output capacitor connected in parallel to a load; a controller controlling the voltage generation units and opening/closing operations of the switches; limitation units configured to limit a time rate of change of a voltage between ends of the a respective switch.
