Web-Based Application for Electric Circuit Analysis

This paper presents web-based application for analysis of electric and electronic circuit. The application is based on PHP scripts and use Spice and Maple with PraCAn package as a computation engine. Continuous-time linear and nonlinear circuits as well as periodically switched linear (PSL) circuits can be analyzed. Results can be obtained in symbolic form for case of linear circuits. Description of the circuit can be entered through graphical schematic editor. It is a Java applet for netlist creation. The whole system is developed at the Department of Circuit Theory, for research and teaching support.
