Applying modified nodal analysis to circuits with inductors and capacitors presents no special difficulty if one uses the complex impedance of these elements. Let us apply MNA to the following circuit (which already has nodes labeled, and the current through the voltage source defined and labeled):
Armed with an understanding of what a node is, what a node poten-tial means, Kirchhoff’s current law, and the concept of a supernode, we will be able to solve some very challenging circuits quite quickly. The node method is entirely derivable from the brute-force anal-ysis method, merely by adding the concept of a node potential.
For example, the circuit in Figure 7.2.9 could be solved using nodal analysis by converting the voltage source and the associated resistance into a current source. That is, E / R1 would be converted into a source I3 with a parallel resistor R1. This is shown in Figure 7.2.10 . Figure 7.2.9 : Circuit with both current and voltage sources.
The node method is entirely derivable from the brute-force anal-ysis method, merely by adding the concept of a node potential. The inputs are the same: the network topology, Kirchhoff’s laws, and the constitutive relations of the circuit elements. A computer could simply accept these inputs and perform the analysis.
Figure 7.2.11 : Circuit for supernode analysis. A supernode is, in effect, the combination of two nodes. It relies on a simple observation. If we examine the circuit of Figure 7.2.11 , the path of the voltage source produces identical currents flowing into and out of nodes a and b.
In the nodal analysis, Kirchhoff's current law is used to write the equilibrium equations. A node is defined as a junction of two or more branches. If we define one node of the network as a reference node (a point of zero potential or ground), the remaining nodes of the network will have a fixed potential relative to this reference.
