A PSpice ® model for a 4-phase, 4-pole air core compulsator was created. With minor modifications it could also model the performance of other pulse alternators. In addition, models for a railgun and switching elements have been created. The models were used to evaluate the system performance of the compulsator and an attached railgun in various configurations with diode rectifiers and SCR's. The process of self-excitation of the machine was also studied. The paper is focusing on the basic theory behind the models as well as techniques for numerical implementation. In addition generic results using normalized parameters are given.

An analysis has been performed of charged transmission-line configurations for use in high-current electron accelerators. Conditions for maximum efficiency and maximum energy transfer to the beam load are derived for ideal constant-impedance lines. It is shown that, in the lossless-line approximation, asymmetric line-pair configurations exist with which both a high accelerating voltage and nominal 100% efficiency can be achieved. The configurations would also have application as a pulse-forming network for use with other switched loads.
