CASE ANALYSIS
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.
Key decisions
- Parallel capacitor bank increases stored energy while keeping ESR low
- Isolation diode prevents the capacitor bank from feeding back into the charger
- SCR switch modeled as high-current SPST to fire the railgun pulse
When to reuse this
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.
