Application of Multisim Software to the Teaching of Linear Circuit Containingcontrolled Sources

The analysis of circuit containing controlled sources is very difficult in the teaching of electric circuits theories.The change of controlled sources' parameters will maybe make linear resistive circuit's solutions nonexistent or infinite and make linear dynamic circuit unstable.In this paper,the relationship between controlled sources' parameters and property of solution of linear resistive circuits and secondorder circuits is discussed by examples.The circuits containing controlled sources are simulated using Multisim software with sweeping controlled sources'parameters and some results are also obtained.The simulative results indicate that it is effective to use Multisim software in analysis of linear circuit containing controlled sources and can help students deepen the understanding of theoretical knowledge.
