Samenvatting

Inductive and capacitive types are the most common pulsed power supply (PPS) topologies. In this paper, the comparison of inductive XRAM generator and capacitor-based (C-based) generator topologies is discussed for the excitation of an electromagnetic launcher (EML). In addition, the effect of capacitance or inductance of the storage element on the load current and laucher efficiency is investigated. The circuit simulation results of these PPS topologies are presented, each of which having 200 kJ PPS energy. The EML used in the study has 0.1 kg total mass of projectile, 3 m long rail. Although the energy density of the XRAM generators is larger than C-based PPSs, the design of an XRAM generator is more challenging than C-based PPS due to the large voltage drop of its opening switches. Moreover, the efficiency of the total system is highly dependent on the design of the storage element. For the XRAM generator, the efficiency is limited by the capability of the opening switches. In this study, using RC snubber circuit, the voltage stress on the GTO (gate turn-off) thyristor opening switches of the XRAM generator is decreased to 2 kV peak voltage, which is available in the market.
