Abstract: With the indirect-feed two-step helicalexplosivemagnetic generator as the initial power source, on the basis of the equivalent circuit pattern, we establish a program named BCYSSYS. The inductance load of the type 04 explosive-magnetic generator was calculated by the BCYSSYS, and the calculated result was compared with the experimental one. Capacitive load was considered. Moreover, utilizing the data sheet of the copper resistivity against specific action during the course of wire exploding, computation was carried out for the inductive energy storage pulsedpower conditioning system with an exploding wire opening switch, in which explosive magnetic generator works as an power source．
