For the PDF version of this article, click here. A switch-mode power supply incurs loss in many areas of its circuitry, including the MOSFETs, input and output capacitors, quiescent controller current ...

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 ...

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 ...

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 ...
