A mathematical model containing no electrical or mechanical losses is analyzed to determine the energy that must be absorbed by the switching element while switching current from a storage inductance of constant value to a railgun. Results are obtained for instantaneous switching and for two different current waveforms for switching over a finite time interval. The results show that the switch must absorb the least amount of energy when switching is instantaneous, and that a linear buildup of railgun current causes more switch energy absorption than a nonlinear buildup. Numerical examples are presented to illustrate values for typical railguns of interest.
