Core loss in inductors can adversely affect system performance. Yet, predicting core loss is a complicated endeavor, especially in complex structures such as coupled inductors. This article examines ...

Have you ever powered up a buck regulator, tested it at full power, then have a permanent reminder left when you perform the inductor finger-tip temperature test? Maybe, excessive core losses and ac ...

Wound-toroid inductors have been the mainstay for desktop core voltage regulators (V CORE) for years. Historically, the bulky size, sloppy tolerances and high power losses of these inductors were not ...

For the PDF version of this article, click here. In all switching regulators, the inductor is used as an energy storage device. When the semiconductor switch is on, the current in the inductor ramps ...
