A main power supply 51 supplies power to a main voltage circuit 5 applying a voltage to an electron gun unit 2a and a collector unit 26, a body power supply 31 supplies power to a body voltage circuit 3 applying a voltage to a body unit 25 and the collector unit 26, and a body power supply stabilization circuit 33 maintains an input/output voltage varying between an electron gun side supply line 51b of the main power supply 51 in the main voltage circuit 5 and a body side supply line 31b of the body power supply 31 in the body voltage circuit 3 at a predetermined output voltage.

A control circuit is applied to the microwave generation device that includes a magnetron (36). The control circuit includes a transformer assembly and a switch portion. The transformer assembly includes a primary winding, a first secondary winding, and a second secondary winding. The primary winding is located at a primary side of the transformer assembly. The first secondary winding and the second secondary winding are located at a secondary side of the transformer assembly. The first secondary winding and a cathode of the magnetron form a filament circuit. The switch portion includes a switch member and a control member. The switch member is located in the filament circuit. The control member is electrically connected to a control winding and configured to control the switch member to turn off or turn on the filament circuit when a current in the control winding changes.
