PSPICE for Thevenin and Norton Equivalents

After the introduction tutorial, continue to use PSpice to analysis the DC Nodal.

 Two voltage Viewpoints

After setting up and simulating the circuit, we run a sweep through the voltage source (evaluating it within a certain range of values). The sweep provides data that allows us to calculate other values.

The circuit for analyzing Thevenin and Norton Equivalents

By running a sweep through the current source named I2 between 0A and 1A. 

When the data from the sweep is presented as a graph, we get the following image.

By sweeping the voltage source between 0V and 1V, we get the above graph.

At 0V, we get 3.335A, which is the Norton current. 

 The following circuit for which we want to find the maximum power transfer.

By sweeping RL from 100 to 5k, we get the following graph.

From this graph, we can see that the curve rises then falls, meaning that the curve has a highest value point. That highest value point is the maximum power.
