Honig, E M; Nunnally, W C

A multiple repetitive railgun power supply for accelerating a projectile at predetermined intervals is described comprising: a serially connected paired parallel rails for guiding the projectile and having an inductive load impedance; powering means for powering the paired parallel rails, each pair of parallel rails therein powered by a single powering means, each powering means comprising; a storage capacitor for providing energy to propel the projectile along the pair of parallel rails the storage capacitor having a first end connected to one rail in the pair of parallel rails and a second end; a storage inductor for providing a circuit with the storage capacitor resonant at a frequency determined by the predetermined intervals for accelerating the projectiles; and a saturable magnetic switch having a low impedance saturated state relative to the inductive load impedance for maintaining energy flow in the resonant circuit formed by the storage capacitor and the storage inductor and having a high impedance unsaturated state relative to the inductive load impedance for transferring energy flow to the pair of parallel rails.
