Temperature regulating method, apparatus, and system of magnetron, variable-frequency power supply, and microwave apparatus

Abstract

The invention relates to the field of microwave apparatuses, in particular, to a temperature regulating method and apparatus of a magnetron, a controller, a variable-frequency power supply, a temperature regulating system of a magnetron, and a microwave apparatus. The temperature regulating method comprises: determining an anode current flowing through a magnetron and an output power of the variable-frequency power supply for driving the magnetron to work; calculating an anode voltage of the magnetron according to the anode current of the magnetron and the output power of the variable-frequency power supply; and adjusting the output power of the variable-frequency power supply based on the anode voltage of the magnetron. Therefore, the anode current of the magnetron is obtained directly toreflect the anode temperature of the magnetron accurately; and the anode temperature of the magnetron is adjusted by adjusting the output power of the variable-frequency power supply, so that over-temperature damages of the magnetron are avoided.

Description

technical field [0001] The invention relates to the field of microwave equipment, in particular to a magnetron temperature adjustment method and its device, a controller, a frequency conversion power supply, a magnetron temperature adjustment system and microwave equipment. Background technique [0002] Microwave equipment is widely used in various fields, including industrial fields, military fields, civilian fields and so on. [0003] Traditional microwave equipment can drive a magnetron to generate microwaves, so that the microwaves affect the load of the microwave equipment. [0004] In the process of realizing the present invention, the inventor found that the traditional technology has at least the following problems: in the process of microwave equipment affecting the load, due to the uncertainty of the load, it will cause the temperature of the magnetron to rise sharply. If no corresponding measures are taken at this time , The magnetron is easily damaged by overhea...
