High-voltage generation apparatus

摘要

A high-voltage generation apparatus raises, when switching from a state where a voltage having a predetermined polarity is output to a state where a voltage having a polarity opposite to the predetermined polarity is output, the voltage having the predetermined polarity in change amounts corresponding to the voltage having the predetermined polarity and a target voltage having the opposite polarity in a transient-state period elapsed until the voltage reaches the target voltage.

1. A high-voltage generation apparatus that outputs a first direct-current voltage having a predetermined polarity or a second direct-current voltage having a polarity opposite to the predetermined polarity, comprising:
an output unit configured to output the first direct-current voltage or the second direct-current voltage; a setting unit configured to set a first target voltage corresponding to the first direct-current voltage or a second target voltage corresponding to the second direct-current voltage; a control unit configured to set a first time period for which voltage is changed in a first change amount and set, after setting the first time period, a second time period for which voltage is changed in a second change amount smaller than the first change amount, in a switching time period for which the first target voltage switches to the second target voltage, in a case of switching from a state where the first target voltage is output from the output unit to a state where the second target voltage is output from the output unit, wherein the control unit changes the first time period and the second time period in accordance with a difference value between the first target voltage and the second target voltage.
