Download this article in PDF format. If you search the internet for “transformer equivalent circuits,” you’ll get five pages of over 100 small circuit diagrams. Figures 1 and 2 show two typical ...

Find the Thevenin equivalent with respect to the terminals a,b for the circuit shown by finding the open-circuit voltage and the short-circuit current. The Thevenin equivalent circuit is shown in the ...

This course introduces more advanced concepts of switched-mode converter circuits. Realization of the power semiconductors in inverters or in converters having bidirectional power flow is explained.

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.

For a more in-depth treatment of this subject, go to “What-circuits-textbooks-haven-t-told-you-about-feedback-amplifier-and-transistor-port-impedances” I recently read the EDN article of Bruce Trump ( ...
