The scenario
A high-voltage DC supply charges a parallel capacitor bank through a current-limiting resistor and isolation diode. A bleed resistor safely discharges the bank when idle, while an SCR trigger switch dumps stored energy through the railgun armature/rails.
What is in this drawing
Read the decisions behind it.
01
Parallel capacitor bank increases stored energy while keeping ESR low
02
Isolation diode prevents the capacitor bank from feeding back into the charger
03
SCR switch modeled as high-current SPST to fire the railgun pulse
Use this template for introductory railgun, coilgun, or pulsed-power discharge circuits where a capacitor bank is charged from a DC supply and triggered into a low-impedance inductive load.
