Abstract

The invention relates to a high-power microwave automatic matching junction. The high-power microwave automatic matching junction comprises a waveguide cavity and a dynamic load; a detection module isarranged on one side of the waveguide cavity; the detection module and a matching module are located on the same side of the waveguide cavity; the dynamic load is connected to a vertical surface of the waveguide cavity away from the detection module; a microwave source is arranged at one end of the waveguide cavity away from the dynamic load; the waveguide cavity comprises a waveguide cover plate; the waveguide cover plate is arranged below the detection module; and a waveguide base is arranged on one side of the waveguide cover plate away from the detection module. According to the high-power microwave automatic matching junction, a driving mechanism is formed between the fixed cavity and servo motors, the fixed cavity is used to install, support and fix the servo motors, and a drive gasket is nested on the screw of the front section of each servo motor to support the stability of the whole servo motor, which is convenient for the operation of the servo motors; and a regulating rodand the waveguide cover are isolated, so that the power capacity of the matching junction is increased, and the purpose of increasing the efficiency of the microwave system is directly realized.

Description

technical field [0001] The invention relates to the technical field of high-power microwaves, in particular to a high-power microwave automatic matching junction. Background technique [0002] The utilization rate of microwave energy largely depends on the impedance matching of microwaves. Traditional microwave impedance matching technology is difficult to achieve real-time, fast and stable matching of dynamic loads, which limits the application of microwave systems in many fields. Using matching junctions It will greatly promote the application of microwave systems in many fields. For example, in microwave plasma systems, microwave plasma sources can be equivalent to the load of microwave transmission lines. [0003] The change of the physical and chemical properties of microwave plasma can be reflected by the change of its impedance. Due to the dynamic characteristics of the plasma load impedance, it is not suitable to manually establish a fixed matching network. At this t...
