GCAP : a generalised circuit analysis program for pulsed power

A completely general circuit simulation code based on state variable analysis is described. The code, designated GCAP, has widespread applications to high peak power and repetition rated systems. In essence, GCAP is a pulsed power equivalent of MICROCAP which retains the full range of analysis options and is applicable also to non-linear and time-varying circuits. Furthermore, GCAP contains a library of commonly-used circuit components and facility for the user to define his own component characteristics. Any circuit consisting of non-linear, time-varying circuit elements can be analysed. Output data is in either tabular or graphics form. GCAP is written in standard FORTRAN and may be run on mainframe or on personal computers.
