Abstract
Electrical parameter such as charging voltage and time series of discharge in repetition-frequency pulse power supply (RFPPS) can be adjusted. In order to obtain the accuracy of launch time and enough muzzle energy, constant current charging technology is taken, which can make RFPPS charge linear and the discharge time same in each discharge cycle. In this paper, the influence factors of accuracy are analyzed. It is proposed to control the accuracy of the charging time by means of the closed-loop feedback of the average charging current. A simulation and experiment of RFPPS test system are established. The results of simulation and experiment show that the charging time is proportional to the charging voltage after pulse-frequency modulation. The launch time can be determined by the charging voltage. Through this way, incoming target will be intercepted if the interception distance and the launching velocity are measured and calculated accurately.
