Abstract
A high-frequency dielectric heating device includes: a high-frequency generating unit to generate a high-frequency electric field; multiple power amplifiers configured to amplify the high-frequency electric field; multiple electrode sections to apply the amplified high-frequency electric field to each of divided areas on a heated material; multiple matching units to detect an incident wave and a reflected wave between the power amplifiers and the electrode sections, respectively, and conduct impedance matching; multiple voltage detecting units to detect a voltage of each of the electrode sections; and a controller to control at least any of the high-frequency generating unit and the power amplifiers in accordance with a voltage, detected by the voltage detecting units, and control a setting for the matching unit such that a reflected wave, detected by the matching unit, is zero in accordance with an incident wave and a reflected wave that are detected by the matching unit.
