Ringing effect analysis of the digital current pulse generator for the linear rail gun

In this paper, transient analysis and design of current pulse generator for the rail gun will be presented. In this paper, the ringing effect will be investigated in detail. Based on the half-bridge circuit, the possible switching pattern causing the ringing effect is verified thoroughly. High frequency switching model will be derived for the linear rail gun. The equivalent circuit model will also be derived to analyze the ringing effect further. Besides, the FPGA Digital implementation for the current pulse control will also be concentrated to get precise timing control for the current pulse generator. By simulation and experimentation, it shows that the ringing phenomena can be observed by way of this developed model. The current pulse is generated successfully with the digital implementation. It is believed that the associated investigation will be useful to improve the performance for the linear rail gun.
