DC-DC Hi-Voltage Converter in application of multi-stage coil gun power charger

Abstract

The multi-stage coil gun is a coilgun with many coils as launchers. Coil gun requires a lot of power to work. High voltage and large currents are needed. Sources of energy to support the coil gun arelimited. Alternatives that are often used by using high voltage capacitors bank. To store energy in a capacitor bank from a battery, a charging device is needed. High voltage DC to DC converter is required. In this article, a high voltage capacitor bank charging device is discussed to supply a multi-stage coil gun. The device has been successfully implemented to support six coilgun levels with the ability to increase the voltage from 12 V to 1.1 kV DC.
