The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

Ferrite pot core transformers are constructed along the lines of the following sketch. We are told that this kind of core is extremely effective at confining the magnetic fields of the transformer ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...

This chapter excerpted from Sevick’s Transmission Line Transformers describes the balun as a subset of transmission line transformers with an in-depth treatment of most used types. Schematics and ...

For the PDF version of this article, click here. Let's return to the question, “Why Have an Air Gap?” initially posed in the Power Design article in the December 2002 issue of Power Electronics ...

As the dashing officer shown above will tell you, early data processing machines and ADP systems employed two types of magnetic cores for memory and other purposes. This 1961 U.S. Army training film ...
