Fusible protection elements have been developed for the 4.5 MJ, Pegasus-II capacitor bank. These fuses are designed to prevent voltage swings of greater than 120% of the maximum capacitor charge voltage -- the maximum permitted reversal is the actual charge voltage minus 1.20 times the maximum allowed charge voltage. This is accomplished without significantly degrading the current wave form except near T{sub 1/4} = {sup {pi}}/2{radical}{ovr LC}. A major portion of the capacitor bank stored energy is dissipated in the protection elements, and the voltage during the interruption process is kept as low as possible -- unlike for high-performance, opening-switch fusible elements.
