Claims

[Claims for Utility Model Registration] By driving the primary winding of the output transformer at high frequency, the output transformer can be
A high frequency generating circuit that generates a high frequency high voltage output in the second winding, and a first high frequency generating circuit that rectifies the high frequency high voltage output to generate positive and negative DC high voltage outputs respectively.
and a second rectifier circuit, and first and second input terminals into which a positive voltage output command signal and a negative voltage output command signal are respectively input, In the high-voltage power supply device that selectively outputs the positive or negative DC high voltage output according to the above, the positive voltage output system includes at least the output transformer and thereafter the first rectifier circuit as the final stage, and the second rectifier circuit. and a negative voltage output system as the final stage, and when the positive voltage output command signal and the negative voltage output command signal are exclusively input to the first and second input terminals, each of these Drive the primary winding of the output transformer on the side corresponding to the signal, and when both signals are input at the same time, drive only the primary winding of the output transformer on the side corresponding to one predetermined signal, or Alternatively, a high voltage power supply device comprising an output control circuit that prohibits driving of the primary windings of both output transformers.
