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.
Claims11
A magnetron oscillating apparatus comprising:
- a magnetron which oscillates a microwave;
- a power supply unit which applies a power to said magnetron;
- a switch circuit which is connected between said power supply unit and a cathode of said magnetron and turned on/off on the basis of a control signal, wherein when said switch circuit is turned on by the control signal, a voltage is applied between the cathode and a grounded anode of said magnetron to cause said magnetron to pulse-oscillate;
- and
- a charge circuit which is connected between the cathode and said switch circuit, wherein a rise time of pulse oscillation of said magnetron is controlled.
