Mass Driver 2 Final Report Part 1 - NASA/SSI

where = energy lost by the recharge capacitor on the nth firing. Therefore the new recharge capacitor voltage for the (n + 1) firing is: Some of the demands placed on the SCR used to do the switching (actually two will be used) are: 1. Voltage rating be at least two times greater than the recharge so as to be able to withstand the voltage reversals on the sector capacitor. 2. The di/dt rating be: 3.
