Electromagnetic launch technology is intended to convert electric energy into armature's kinetic energy. To make the armature accelerated smoothly, PFN (pulse forming network) needs to generate a flattop wave by triggered sequentially. The thyristor in PFN is easy damaged under this condition. The thyristor's reverse recovery process is the critical reason for its damage. The paper expounds the thyristor's...
To analyze the electric parameters of a pulsed power supply (PPS) system and their influence on muzzle velocity, a stable and reliable 200-kJ compact PPS system used for electromagnetic railgun system has been developed. The PPS system consists of ten modules, and each module is comprised of a high energy density capacitor (3270 $\mu $ F/3.5 kV), 4-in thyristor, a pulse shaping inductor (1.5 $\mu $ ...
The Electromagnetic gun (EMG) system needs a compact pulsed power supply system, which should supply high energy and large current. The paper presents a setup of a compact pulsed power supply system used for EMG system, which is based on high energy density capacitors. The pulse forming network consist of ten 50 kJ modules, which can be triggered in sequence. Each module is composed of a high energy...
