Design and electromagnetic analysis of an induction-type coilgun system with a pulse power module

This paper discusses the design and electromagnetic analysis of an induction-type coilgun system with a pulse power module. The voltage, current, force, velocity, acceleration, and efficiency of the coilgun system were analyzed using the finite element method (FEM). Based on the results of the electromagnetic analysis, the geometry of the coilgun system was defined. The electromagnetic analysis results were also compared with the mathematical analysis results. The designed coilgun system was found to exhibit high energy efficiency and safe against the force and temperature of the coils. The design specifications and analysis results concerning the coilgun can hence be effectively utilized to develop a large-scale multi-stage induction-type coilgun system.
