A Lumped Parameter Model and Its Code for Capacitor-Based Railgun With Arbitrary Number of PFUs

Abstract

A lumped parameter model of capacitor-based railgun (CBRG) with arbitrary number of pulse-forming units is created and design of its simulation code is introduced. To show simulation and optimization capabilities of the code, two applications of the code are given. In the first example, a CBRG with topologically created pulse-forming network is simulated and the results are analyzed to show the availability of the code. In the second example, genetic algorithm-based and iteration-based methods on optimizing timing sequence of pulsed-power supply system are introduced and compared, and influence of timing sequence on launching performance is discussed. Finally, it is concluded that the iteration-based method has preferable effects on calculating timing sequence under the constriction of flat-topped rail current.
