To increase the energy-transfer efficiency from the initial charging system to the helical magnetic flux compression generator（ HMFCG）,the charging circuits before and after prying-brokenswith off are analyzed. Equivalent circuit models of direct and indirect charging methods are built and equivalent equations are solved by introducing the relevant data of some HMFCG prototypes. The variation trend of the charging current,the initial coupling magnetic flux,the capacitor counter voltage and the output current are discussed at different circuit parameters,and some technical requirements on device designing are given. Research results show that the method is helpful for increasing the output performance of small-middle size HMFCGs.
