御手段を備えたことを特徴とする高圧電源装置。[Claim for Utility Model Registration] Switching the DC voltage obtained by rectifying the commercial power supply voltage in a switching unit, boosting the switched signal in a step-up transformer, and charging a capacitor with the secondary side voltage of this step-up transformer. In a high-voltage power supply device that obtains a high voltage across a capacitor, overcurrent detection means is provided on the primary side of the step-up transformer for converting an increase or decrease in the primary side current into a voltage signal and outputs the voltage signal, and this overcurrent detection means 1. A high-voltage power supply device comprising control means for responding to the output of the overcurrent detection means and applying a feedback signal to the switching section so that the output of the overcurrent detection means is constant.
