Problems solved by technology

[0003] For most power supplies, the load is highly unknown, so its closed-loop control algorithm has strong adaptability, which causes the problem of lack of pertinence, and cannot well meet the working requirements under special loads.

Especially for the traveling wave tube load similar to the transmitter, its working state alternates between heavy load and light load at high frequency, and its own characteristics make the system closed-loop controller only suitable for collecting voltage feedback parameters, and it is difficult or inaccurate to obtain current parameters , the disadvantages that lead to the response speed of the common control algorithm not fast enough often appear in the work, such as the slow voltage recovery speed at the beginning of the application of radiation, when the adjustment parameters take care of the response speed, the jitter will increase during the radiation process, etc., it is difficult to take care of all aspects of the system
