A variety of linear models are available to represent common active electronic devices such as transistors and vacuum tubes. Devices operating under large-signal conditions often require nonlinear ...

In this Design Idea, we explore several ways to use SPICE [1-3] circuit analysis software to determine the Thevenin and Norton equivalent circuit parameters of linear active networks. The Thevenin ...

This course introduces the basic concepts of switched-mode converter circuits for controlling and converting electrical power with high efficiency. Principles of converter circuit analysis are ...

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 ...

What is hard about analyzing feedback circuits is the extraction from the circuit diagram of the simple block diagram found in active circuits and control textbooks. To start with a relatively easy ...

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.
