Voltage application device includes voltage application circuit. Voltage application circuit causes discharge electrode to generate a discharge by applying an application voltage to load that includes discharge electrode holding liquid. Voltage application circuit periodically changes a magnitude of the application voltage to generate a discharge intermittently. Voltage application circuit applies a maintaining voltage to load for suppressing contraction of liquid in addition to the application voltage during an intermittent period from a discharge to a next discharge.

Voltage application device and discharge device

A voltage application device includes a voltage application circuit. The voltage application circuit applies application voltage between discharge electrode and counter electrode which face each other with a clearance left from each other to generate a discharge. The voltage application device forms discharge path partially and dielectrically broken between discharge electrode and counter electrode when a discharge is generated. Discharge path includes first dielectric breakdown region formed around discharge electrode, and second dielectric breakdown region formed around counter electrode.

Voltage application device includes voltage application circuit. Voltage application circuit applies a voltage to load including discharge electrode that holds liquid, voltage application circuit generating discharge in discharge electrode. During a drive period, voltage application circuit periodically changes a magnitude of the voltage applied to load at a drive frequency within a predetermined range including a resonance frequency of liquid, voltage application circuit mechanically vibrating liquid.
