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

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.
