A class of explosive-driven flux-compression generators, called strip generators, has been developed for railgun power sources. We describe the construction of these generators and note simple geometric variations that can be made to alter their output pulses. Current wave forms are presented together with various current integrals that help determine their most useful ranges of applicability in powering railguns. A useful generator calculational model is also described. The model includes the effect of generator component displacements from magnetic forces, has provisions to allow for flux losses at the moving contact point, and also calculates the high frequency inductance of the generator
