The authors describe an innovative concept for recovering the electrical energy remaining in an inductive energy storage system, such as that left in the barrel of a railgun after the projectile has exited the gun. Previously discussed recovery schemes generally use a capacitor bank that is capable of storing all the energy to be recovered. The authors describe a circuit that recovers the energy in multiple parcels, each being a small fraction of the overall energy. This concept, referred to as multicycle resonant energy recovery, allows a significant reduction in the size and weight of the intermediate energy storage elements. The basic circuit and its operation are discussed as well as criteria for component selection, scaling, and trade-offs. Results from a computer simulation of the application of the circuit to a railgun model are presented.
