<P>PROBLEM TO BE SOLVED: To provide a high voltage generating circuit which can suppress variation in high voltage output with simple circuitry, and to provide an ion generator and an electrostatic atomizer. <P>SOLUTION: A resonance suppression section 21 for suppressing the impact of resonance is connected in parallel with a switching section 14. The resonance suppression section 21 suppresses the impact of resonance by lowering the oscillation frequency of a primary voltage set by a high voltage control signal below the resonance frequency of a step-up section 15, and the step-up section 15 sets a frequency capable of stepping up at a predetermined high voltage. For high frequency ringing generated by the inductance in the step-up section 15 of a high voltage generating section 9, the resonance suppression section 21 short-circuits the high frequency components by means of a capacitor 23 and attenuates the high frequency components by means of a resistor 22 thus clearing the resonance component from the resonance frequency of the high voltage control signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
