<P>PROBLEM TO BE SOLVED: To raise a high voltage without generating an overshoot or an undershoot, and to make an output voltage reach a target voltage in a short time. <P>SOLUTION: The high voltage generator raises a DC voltage at a variation ratio variably set in advance according to a target voltage without performing feedback control during a period of a transient state from the outset of output of a high DC voltage till attainment of the target voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
