Abstract
A high voltage power supply may include a switching unit, a voltage resonant unit, a connection part, a rectifier unit, a voltage amplifying unit, a voltage output unit, and a frequency control unit. The switching unit is driven per a frequency signal. The voltage resonant unit is connected to the switching unit and includes an inductor, to which a voltage is applied, and a capacitor. The connection part connects the switching unit and the inductor. The rectifier unit includes a diode that is connected to a power-supply voltage side of the inductor via a capacitor. The voltage output unit outputs a voltage obtained from the voltage amplifying unit. Moreover, the frequency control unit controls a frequency of the frequency signal per a control signal used to set a voltage output from the voltage output unit and an output signal output from the voltage output unit.
