This paper designs a kind of 25KV adjustable DC
generators. The DC high voltage generator of the designing
adopts the technology of linear regulator; voltage doubling
rectifier technology produces the output voltage of the wide
range of high stability. The generator has strong versatility,
safety and economy. Through the simulation analysis, the DC
high voltage generator outputs stable amplitude for DC high
voltage 25KV through the divider in 0.1ms time , the maximum
output power is 12.SW, the output resistance is SO Mil The
experiment shows that the DC high voltage generator can meet
the design requirements.
