MODELLING AND STUDYING TRANSIENT STATE OF SIMPLE SYSTEMS WITH LABVIEW.

This paper presents virtual instruments to simulate the transient state for some simple and complex circuit. The relative short event between different steady states is the transient state which is followed by energy variation in the circuit. This energy variation produces impulses which propagate through the net and influence other devices. Because there are a lot of equipments operating in switching mode, it is important to study the transient state. To model and study the transient state equations for circuits were written. The article presents the mathematical base of the transient state and types of response of the transient state. The main part is to present the developed virtual instruments for electrical circuits to simulate and to study their transient state. The virtual instruments were developed in LabView. The virtual instruments allow setting different circuit configurations, different values for circuit elements and show the results in analytical and graphical way. [ABSTRACT FROM AUTHOR]
