Abstract

The authors outline two XRAM (MARX spelled backwards) circuit concepts and discuss the distributed energy and multishot aspects of the hybrid concept. The hybrid XRAM circuit minimizes switching requirements while retaining the positive benefits of the conventional XRAM circuit. It also provides a smooth rising current waveform which is useful for electromagnetic and electrothermal gun research. The authors also describe a more detailed study of a battery-powered hybrid XRAM current doubler design being considered for use as a general-purpose laboratory inductive energy supply, operating at up to 2.5 MA with as much as 10 MJ of electrical energy stored. Resulting waveforms are shown and benefits derived from the use of this circuit are compared to those from a conventional XRAM current doubler as well as from a direct, inductive store, system design
