The open-circuit voltage vOC is simply vT because no voltage drops across RT when i = 0. To find the Thevenin equivalent resistance RT, remove all power sources and calculate the total resistance ...

In this Design Idea, we explore several ways to use SPICE circuit analysis software to derive the Thevenin and Norton equivalent circuit parameters of linear active networks.

Thévenin Equivalent Circuits If you’re not content with my hand-waving explanation of the circuit above, you’ll need to know a little bit about Thévenin equivalence, but it’s not that bad.

This course teaches how to design a feedback system to control a switching converter. The equivalent circuit models derived in the previous courses are extended to model small-signal ac variations.

This article looks at the equivalent circuits for quasi-resonant cookers and coil characteristics relating to the various pan materials used in these implements.
