Abstract
The power supply apparatus including a high-voltage generation unit generating a DC voltage VA includes a Zener diode that drops the DC voltage VA to a DC voltage VB, a resistor connected to a line to which the DC voltage VA is output, and a voltage divider that generates a DC voltage VC by dividing the DC voltage VA with the resistor, and the voltage divider adjusts the DC voltage VC such that the potential difference between the DC voltage VB and the DC voltage VC is within a predetermined range.
Claims11
A power supply apparatus comprising:
- a voltage generation unit configured to generate a first DC voltage;
- a voltage-drop element configured to drop the first DC voltage to a second DC voltage;
- a first resistor connected to a line to which the first DC voltage is output;
- and
- a first voltage dividing unit configured to generate a third DC voltage by dividing the first DC voltage with the first resistor,
- wherein the first voltage dividing unit includes an adjusting unit configured to adjust the third DC voltage so that a potential difference between the second DC voltage and the third DC voltage is within a predetermined range.
