Title: Repetitive resonant railgun power supply

Abstract

A repetitive resonant railgun power supply provides energy for repetitively propelling projectiles from a pair of parallel rails. The supply comprises an energy storage capacitor, a storage inductor to form a resonant circuit with the energy storage capacitor and a magnetic switch to transfer energy between the resonant circuit and the pair of parallel rails for the propelling of projectiles.

  • A repetitive resonant railgun power supply provides energy for repetitively propelling projectiles from a pair of parallel rails. The supply comprises an energy storage capacitor, a storage inductor to form a resonant circuit with the energy storage capacitor and a magnetic switch to transfer energy between the resonant circuit and the pair of parallel rails for the propelling of projectiles.
  • A repetitive railgun power supply for accelerating a projectile at predetermined intervals is described comprising: a pair of parallel rails for guiding the projectile and having an inductive load impedance; 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, the storage inductor having a first end connected tomore » the other rail in the pair of parallel rails and a second end connected to the first end of the storage capacitor; 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. The magnetic switch has a first end connected to the first end of the storage inductor and a second end connected to the second end of the storage capacitor and has a volt-second capacity effective to maintain the high impedance state during the accelerating projectile and to switch to the low impedance state when an arc is formed between the rails as the projectile exits the rails.« less
  • A multiple repetitive resonant railgun power supply provides energy for repetitively propelling projectiles from a pair of parallel rails. A plurality of serially connected paired parallel rails are powered by similar power supplies. Each supply comprises an energy storage capacitor, a storage inductor to form a resonant circuit with the energy storage capacitor and a magnetic switch to transfer energy between the resonant circuit and the pair of parallel rails for the propelling of projectiles. The multiple serial operation permits relatively small energy components to deliver overall relatively large amounts of energy to the projectiles being propelled.
