Analysis of the Triggering Instants of the Solid-State Switches of the Pulsed Power Sources for Achieving Optimal Projectile Velocity in a Multistage Induction Coilgun

Abstract: The coils of each stage of a multistage induction coilgun must be precisely and appropriately synchronized to achieve a higher launch velocity (vp) of the projectile. Hence, the optimum ...
