Web-Based Application for Analysis of Electrical Circuits and Systems

This paper presents web-based graphical schematic editor for analysis of electric and electronic circuits. Continuous-time linear and nonlinear circuits as well as periodically switched linear circuits can be analysed in this editor. In case of linear circuits, results can be obtained in symbolic form. The editor uses Spice OPUS and Maple software with PraCAn package as a computation engine. All circuits created in this editor can be turned into functional blocks that can be subsequently edited through programming code. The editor contains a model of ideal, linear and nonlinear operational amplifier. The whole system is developed at the Department of Circuit Theory, for engineering education and research support.
