The pulsed power supply (PPS) is one important component in the electromagnetic launch system. The inductive PPSs have attracted researchers' attentions with the major advantages of high energy storage density (over the capacitive PPSs) as well as simple structure and easy control (over the rotating mechanical PPSs). As for the inductive PPSs, the circuit topology of the basic module will directly determine the comprehensive performance of the whole system. From the perspectives of working principles, strengths, weaknesses, and comprehensive performance, this paper presents a historical and technical review of the major circuit topologies for the inductive PPSs.

Three-dimensional (3-D) numerical simulations have been carried out taking into account the magnetohydrodynamics (MHD) effect of the railgun plasma armature. The 3-D space-time conservation element and solution element (CE/SE) method is derived for solving the coupled Navier-Stokes equations and Maxwell equations. The results show that a steeper gradient of the magnetic field and pressure that appears along the direction of the rail can be observed. The temperature distribution is affected by the boundary conditions for the radiative heat flux, with the maximum temperature appearing in the center near the base of the projectile. Circulation patterns of velocity that are evident in both the rail-to-rail plane and the insulator-to-insulator plane result from the convection and unbalanced force between the Lorentz force and pressure gradient. The periodical variation of the temperature and acceleration is obvious until a new steady state is achieved. This model can efficiently evaluate the dynamics of the plasma motion, and provide a basis on understanding the much more complex physical phenomena.
