It is necessary to make full use of explosive energy and reduce the loss of unnecessary energy when we study high-powered radio frequency explosive magnetic flux compression generator . Therefore, this paper proposed that indirect charging was used in radio frequency explosive magnetic flux compression generator. Based on the equivalent circuit theory, we studied the interaction of two loops in the case of indirect charging. The numerical simulation results showed that we must choose appropriate circuit parameters of charging in order to guarantee the radio frequency explosive magnetic flux compression generator to run steadily.
