Symbolic analysis of nonlinear electronic circuits by PraCAn package in Maple program

This paper presents a special package for Maple program designed for electric and electronic circuit analysis. The package contains functions for analysis of continuous-time linear and nonlinear circuits as well as periodically switched linear circuits. The method of analysis is based on modified nodal voltages method. Results can be obtained in symbolic or semisymbolic form. This contribution introduces possibilities of the package for nonlinear circuit symbolic analyses. Simplification of active element models can be made by special package option to obtain useful results for dominant circuit behavior. This is demonstrated on elementary examples of nonlinear DC analysis and AC analysis of linearized circuit. The package was developed at the Department of Circuit Theory, for research and teaching support.
