Abstract: Discharge device includes voltage application circuit that applies output voltage to load including discharge electrode holding liquid to generate discharge in discharge electrode. Voltage application circuit includes a function of varying a magnitude of output voltage, and a function of switching a discharge period that is a period for varying the magnitude of output voltage to any one of a plurality of periods having different lengths with a lapse of time.

Abstract: A resonant circuit in an inverter includes a first resonant circuit configured with a heating coil and a first resonant capacitor connected in series to the heating coil, a second resonant circuit configured with the first resonant circuit and a second resonant capacitor connected in parallel to the first resonant circuit, and a resonance choke coil connected in series to the second resonant circuit. The resonant circuit is configured so that impedance of the heating coil and the first resonant capacitor is set to be close to impedance of the second resonant capacitor, at a frequency of a current flowing through the heating coil. Thus, an object to be heated can be efficiently induction-heated without an increase in a current flowing through the switching element.

Abstract: Discharge device includes discharge electrode, voltage application circuit, and current limiting element. Discharge electrode is disposed to face counter electrode, and retains liquid. Voltage application circuit is electrically connected to discharge electrode and counter electrode with discharge electrode as a ground side. Voltage application circuit generates discharge between discharge electrode and counter electrode by applying a voltage between discharge electrode and counter electrode. Current limiting element is electrically connected to a side of discharge electrode opposite to counter electrode. Current limiting element limits a current flowing to discharge electrode.
