This study introduces a segmentation methodology for the coilgun structure which enhances the energy utilization along the propulsion track. It is enabled by a low voltage modular rapid capacitor charger with segmented voltage bus, and peripheral circuits to achieve accurate timing sequencing. The resultant system is of significantly higher power density and potentially capable of producing higher velocity propulsion per unit volume.The concept and circuitries are described in detail. Experimental validation is provided for a 1KW rated rapid capacitor charger prototype, that charges 3x1mF serially connected capacitors to 1200V from a 12V input source.
