Accurately predicting core losses in magnetic components is difficult, and no less challenging in composite inductors. Several core loss models are available, all of which have their merits. This ...

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 ...

In the second part of this two-part article, the authors describe how to determine the efficiency losses associated with passive components and how features offered by controller ICs can be used to ...

We report a fabrication technology for 3D air-core inductors for small footprint and very-high-frequency power conversions. Our process is scalable and highly generic for fabricating inductors with a ...
