[Abstract]:As the most important components of radar transmitter, accelerator and microwave source, the performance parameters of high voltage pulse modulator have great influence on the whole system. At the same time, with the development of microwave devices and the expansion of applications. The parameters of pulse modulator are required more and more, and the performance of high voltage pulse modulator is becoming more and more important. In recent years, with the rapid development of electronic devices, a variety of integrated circuits continue to appear. On the basis of the traditional linear modulator technology, the new pulse modulator technology is also gradually maturing, and its control system is gradually in the direction of networking. Based on the task requirement of a high stability microwave pulse power supply, this paper takes the realization of high pulse stability pulse output and new high reliability control system as the main research object. In the process of completing the design of the whole microwave pulse power supply system, the following research work is carried out in detail. 1. The design scheme and working principle of the traditional linear modulator are studied. On the basis of the analysis of its shortcomings and limitations, a new constant current charging power supply as a pulse modulator power supply is proposed, and the advantages of a new constant current charging power supply realized by series resonance are analyzed in detail. Working principle and design scheme. Finally, the hardware scheme design and detailed parameter calculation of microwave pulse power supply system are completed. According to the output pulse stability parameter, the main factors and reasons that affect the performance of microwave pulse power supply system are analyzed.
