Disclosed is a microwave oven comprising a magnetron having an anode, a cathode and a filament, and a high voltage transformer having a primary coil and a secondary coil for supplying a high voltage to the magnetron. The microwave oven comprises a capacitor connected in parallel to the secondary coil of the high voltage transformer, forming a resonance circuit with the secondary coil. With this configuration, the performance of the magnetron is maintained by lowering the anode peak voltage applied thereto during the early non-oscillating period, and the circuit elements are protected from damage by removing the surge voltage.
