Abstract:
A cooking apparatus includes: a receiving coil configured to receive power wirelessly, a first rectifier configured to rectify power transmitted from the receiving coil, a first DC capacitor connected to an output terminal of the first rectifier, a working coil, an inverter, a second DC capacitor connected to an input terminal of the inverter, and a filter circuit connected between the first DC capacitor and the second DC capacitor and configured to block a noise current that flows between the first DC capacitor and the second DC capacitor and that is associated with a predetermined frequency or a frequency higher than the predetermined frequency. The inverter is configured to convert power from the second DC capacitor into an alternating current and transmit the converted alternating current to the working coil.
