Application for Symbolic Analysis of Linear Circuits Including Switched Circuits

Abstract: This paper presents a tool for symbolic analysis of electronic circuits – continuous-time circuits and periodically switched linear (PSL) circuits. Applied method of analysis is based on modeling of periodically switched networks by mixed s, z description. The method is implemented in program MapleTM in the form of Maple package named PraSCAn. Current version of the package provides all basic analysis of linear continuous-time circuits as well as of multiphase PSL circuits. The paper presents time domain analysis of idealized switched circuits in more detail. Described algorithm uses closed-form solution in time domain for continuous time which is implemented in the package. A system of www interface based on PraSCAn package for electronic circuit analysis via internet is presented in the next part of the article. Some results are shown in the end of the paper.
