Optimization and Analysis of Energy Conversion Efficiency in Single Stage Pulse Induction Coilguns

In order to gain the rule between them, the mathematic model of single stage pulse induction coilguns is built, and the launch process is simulated and analyzed. The electrical-to-kinetic energy conversion efficiency of system is regarded as a target function, and the initial position of the armature, the discharge voltage and the capacitance of capacitor banks are regarded as variables. Results of analysis indicate that the time of projectile to be accelerated in the drive-coil should match the time of current rising in the drive-coil. As a rule, the high energy conversion efficiency can be gained in the system with capacitor banks of high voltage and low capacitance.
