| Abstract |
Advances in wide bandgap semiconductor technologies have enabled increased switching frequencies,which is critical for reducing size of passive components in power supplies. These advances in powerconversion technologies have highlighted the need for development of new class of magneticscomponents (inductors, transformers etc) with lower footprint and higher efficiency. Presently, thesizes of these magnetic components have been limited due to the use of low flux density ferrite as acore material. In this paper, we present the assembly and working of a nanocrystalline thin filminductor with low loss performance as a replacement for ferrite based inductors. The performance ofthe thin film inductor is characterized in a commercial 500 kHz evaluation board. The paper alsoshows the significant reduction in footprint with the thin film inductor using an oxide as insulationbetween magnetic layers. |
