Abstract: The launching of the railgun needs enough amplitude and width trapezoid wave current. This article presents three working modes of two inductive pulsed power supplies supplying one load. The load current magnification and the pulse width increment are different under these three different working modes. Simulation and experiment results show: the load current magnification is the largest and the pulse width increment is the smallest when two STRETCH meat grinder modules work at the same mode; the load current magnification is the smallest and the pulse width increment is the largest when the main switches of two STRETCH meat grinder modules open simultaneously and the thyristor of the second model delays the first one; the load current magnification and the pulse width increment is medium when the second model delays the first model. From the results we can get the right current by choosing the appropriate triggering.
