ABSTRACT:
A magnetron oscillating apparatus includes a magnetron, power supply unit, and switch circuit. The magnetron oscillates a microwave. The power supply unit applies a power to the magnetron. The switch circuit is connected between the power supply unit and the cathode of the magnetron and turned on/off on the basis of a control signal. When the switch circuit is turned on by the control signal, a voltage is applied between the cathode and the grounded anode of the magnetron to cause the magnetron to pulse-oscillate.
