特徴とする高圧電源。[Scope of Claim for Utility Model Registration] 1. A high-voltage power supply for an electron microscope, etc. is equipped with a control system that detects the output voltage and applies negative feedback to stabilize the output voltage. A high-voltage power supply characterized in that a signal for setting an input voltage commensurate with an output voltage from outside the feedback loop and a negative feedback signal of the output voltage are added to form a final feedback signal. 2. In claim 1, a limiting function is provided to limit the range of the negative feedback signal of the output voltage so that an unnecessary amount of negative feedback signal does not enter, and to prevent the generation of a voltage abnormally higher than the set output voltage. A high voltage power supply characterized by:
