The scenario
A capacitor bank is charged through a current-limiting resistor and charge switch, then discharged through a railgun rail pair and sliding armature via a high-current fire switch.
What is in this drawing
Read the decisions behind it.
01
Use a capacitor bank charged through a resistor and SPDT charge switch
02
Model rail pair as series R-L with armature resistance
03
Add freewheeling diode across inductive discharge path
Reuse for pulsed power or electromagnetic launcher schematics needing charge/discharge isolation and inductive load clamping.
