Abstract:
The reverse charging of stored energy capacitor will occur in the course of discharging in the pulse power supply system.And the reverse voltage on the stored energy capacitor has no way be released due to unidirectional break over character of power switch,so the stored energy capacitor will be damaged and the efficiency of power will be reduced.The discharging course of the stored energy capacitor was analyzed and the factors effecting reverse voltage were discussed in this paper.In order to release the reverse voltage on the capacitor,the power switch was adjusted from capacitor spur track to load spur track.The results of simulation and experiment show that the load current characteristics are identical between the rectified pulsed forming network( PFN) and the primary PFN.So the rectified PFN meet the requirement of electromagnet launching system,and at the same time the longevity of stored energy capacitor and the efficiency of electromagnet launching system are increased.
