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 ...

Power electronics are rapidly expanding into new applications as high-power semiconductor devices increase their rated operating current and frequencies to higher and higher levels. As a basic ...

Inductors are deceptively simple. However, a closer look reveals underlying complexity. How else can you explain the many types of core materials, types of windings, sizes, geometries and wide range ...

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 ...
