“…As an essential element of the power system, there is also the way the energy is delivered, which can be divided into two main categories: the first releases all the energy at the same time, while the second allows the energy to be divided into several smaller pulses [19]. An example of an inductive power supply is the XRAM generator, which uses inductive coils to multiply current by charging them and then quickly switching [20]. Another solution is the compulsator, which uses rotational momentum to store kinetic energy and then transfer it as a current pulse [21].…”

The influence of the capacitor configuration in the pulse supply system for rail accelerators on its efficiency was investigated in the paper. Two different configurations were compared: the first with a parallel connection of capacitors and the second with a parallel-series connection. In both cases, the same number of capacitors was assumed. All other parameters of the device were kept constant, i.e. mass and dimensions of the armature, rail length and stator geometry. A field-circuit model was used to analyse numerically the transients for different capacitor configurations and voltage values. The model was verified experimentally.

“…However, the low power density and powerful rotational inertia make it unsuitable for mobile platforms such as chariots [4]. The inductive PPS has the advantage of high energy density and small volume, and mainly adopts the Meat Grinder circuit to improve the current [5]. Therefore, the inductive PPS is greatly affected by the coupling coefficient.…”

Utilization Optimization of Capacitive Pulsed Power Supply in Railgun

The excitation pulse current used to drive the railgun needs to present very a high magnitude (hundreds of kA) flat-top with very low ripple. At present, the main method to obtain this current is to increase the number of the capacitive pulsed power supply (PPS) modules. However, low utilization and massive volume of the railgun system would occur with this method, hampering the application of railgun. Therefore, the utilization optimization technology of PPS is researched in this paper. In order to obtain highly stable flat-top current, the control strategy of the capacitive PPS is designed, and a new charging voltage configuration is proposed, which significantly decreases the use of the capacitive modules. Besides, a miniaturization transformation scheme of capacitive PPS is proposed based on the control strategy. The result shows that the flat-top current ripple has the biggest influence on the PPS utilization, and the smaller the flat-top current ripple, the lower the utilization. When the current with 200 kA magnitude and 0.75% flat-top current ripple is achieved, an 81.9% decrease of volume and a 428.7% utilization improvement are achieved through miniaturization transformation.
