Abstract: 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.

Abstract: 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.
