摘要： In a high voltage power supply that does not use a transformer. An output voltage can be appropriately adjusted in accordance with a load change.
A switching element; a voltage resonant circuit that includes an inductor, to which a voltage is applied when the switching element is driven, and a capacitor; a rectifier circuit that includes a capacitor and a diode that output a high voltage in accordance with a resonance operation of the voltage resonant circuit; and a high voltage power supply that performs control in such a manner that a driving frequency of the switching element can be changed in accordance with an output from the rectifier circuit and a control signal used to set an output voltage.
