In this paper, the transient analysis and design of a current pulse generator for a rail gun is presented. In this paper, the ringing effect is investigated. 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. An FPGA digital implementation for the current pulse control is also concentrated upon to obtain 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 is useful to improve the performance for the linear rail gun.
