Inductor Core Technology Shrinking Power Supplies
Jul 1, 2002
Washer-shaped toroids meet the inductor requirements for compact power supplies - low height, low core cost, single-piece core assembly, good heat dissapation, no bobbin, and good shielding....
CAD/CAE Software Aids Converter Design
Jul 1, 2002
Before the availability of computer-aided engineering software designed to run on PCs, engineers had little choice but to simplify assumptions for ballpark estimates of system performance. As a result, magnetic circuit analogies were used in place of true field analysis, and frequency response methods were used to evaluate stability in place of actual transient analysis....

Demystifying Buck Inductors
Jul 1, 2001
A buck inductor is nothing more than a wound inductor normally used in switchmode power applications to step a dc voltage source down to a lower level. However, it's just a little more complex than that....
Fe-Si-Al Powder E-Cores Compete with Gapped Ferrites
Jul 1, 2001
Magnetic cores for power supply inductors require careful selection because of the important role they play. An inductor core must be able to retain inductance...
