Problems solved by technology

However, adjusting the high voltage and magnetic field according to the power requirement will affect the frequency, and adjusting the frequency according to the frequency requirement will also affect the power. Therefore, these three adjustment processes affect each other, and it is difficult to achieve precise adjustment of power and frequency

Abstract

The invention provides a method for controlling a magnetron at set power. The magnetron is coupled to a high-voltage modulator and an electromagnet coil. The method comprises the steps of receiving set needed power of the magnetron; generating a detection signal corresponding to the set needed power; setting high voltage of the high-voltage modulator and current of the electromagnet coil according to a corresponding relationship between pre-stored output power of the magnetron and high voltage of the high-voltage modulator and current of the electromagnet coil; comparing a sampling signal corresponding to the actual output power of the magnetron with the detection signal corresponding to the set needed power; if the comparison result is inconsistency, adjusting the high voltage of the high-voltage modulator and the current of the electromagnet coil, and making the actual output power of the magnetron reach the set needed power.

Description

technical field [0001] The invention relates to the field of magnetrons, in particular to frequency and / or power control of magnetrons. Background technique [0002] figure 1 A prior art control assembly 10 is shown coupled to an accelerator tube 20 . Specifically, the control assembly 10 includes a magnetron 11, a high-voltage modulator 12 coupled with the magnetron 11, an electromagnet coil 13, a transmission waveguide 14, a coupler 15 coupled with the transmission waveguide 14, and a Isolator 16. Specifically, the magnetron 11 is coupled to the accelerating tube 20 through the transmission waveguide 14 , the coupler 15 and the isolator 16 . Among them, the aforementioned high-voltage modulator 12 can provide high voltage; the electromagnet coil 13 can provide a magnetic field when the electric current is fed into the circuit separated by the separate electromagnet power supply 17 or the high-voltage modulator 12; Microwaves of a certain power and frequency can be gene...
