High voltage capacitor charging system applied for multi-stage coil consisting of a coil arrangement as a launcher and requires much energy to work. However, large currents and the high voltage required are very limited. High voltage capacitor banks are used as an alternative for energy storage. This capacitor bank is supplied by batteries and requires a charging device. The process of charging a high voltage charging capacitor requires a DC-DC Converter device. In this article, to supply energy to the coilgun, a High Voltage Capacitor Bank is used. 10 capacitors are connected in parallel charging the capacitors with a voltage divider system to avoid swelling at the capacitor charge. This device has been successfully implemented in Multistage Coil Gun. The results achieved indicate an increase in voltage capability up to 1.8 kV DC.

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.
