Abstract

Predicting railgun performance is challenging due to dynamic rail resistance variability. This study addresses this by designing and analyzing a high-performance Capacitive Pulsed Power Supply (CPPS) with Zero Voltage Switching (ZVS), and quantifying the railgun's performance variability using simulation. A comprehensive model of the railgun and its custom CPPS (750V-4kV, 200kHz resonant full-bridge with 346ns dead time, 3-stage Cockcroft-Walton) was developed in PSIM. The CPPS achieved high switching efficiency and stable power delivery. Railgun simulations showed electromagnetic force and acceleration peaking sharply before decaying, while armature velocity increased linearly to ~1.6 m/s at 0.01 seconds. This research offers a realistic understanding of railgun performance, underscoring the critical impact of dynamic rail inductance and the importance of accounting for such uncertainties in future designs for improved predictability and reliability.
