Transient analysis and design 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 is presented. In this paper, the ringing effect is investigated in detail. Based on the half-bridge circuit, the possible switching pattern causing the ringing effect is verified thoroughly. A high frequency switching model is derived for the linear rail gun. The equivalent circuit model is also derived to analyze the ringing effect further. Besides, the FPGA digital implementation for the current pulse control is also concentrated on to get precise timing control for the current pulse generator. By simulation and experimentation, it is shown 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.
