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 ...

In addition, because the coupled inductor is made using a ferrite-core material, the core losses can be reduced by a total of 1.7 W, which represents a 2% to 3% increase in system efficiency.

Three-phase LLC converters are candidates for efficiency and power density gains. Conversion from 270-28Vdc requires isolation. A popular choice of power converter topology might be the LLC type ...

E-core shapes allow assembly ease. Nienchtze Teng, Magnetics Div. Spang, Butler, Pa. Magnetic cores for power supply inductors require careful selection because of the important role they play. An ...
