Power architectures with nonisolated voltage regulation continue to evolve, and power inductor designs are fundamental to the success of the new product designs. The trend toward two-stage conversion ...

This application note presents the types of core materials used in power inductors. It also briefly discusses the core saturation, core loss, as well as the Equivalent Series Resistance (ESR). This ...

TDK has introduced ferrite ‘E’ cores up to 40 x 80 x 160mm for industrial applications such as motor drives. The largest one is made from N87 ferrite, while most of the rest also come in N88 or N97.

The widespread use of gapped ferrite cores for inductive components subject to a superposed dc current poses a challenge to the way the required properties are specified. The importance of attaining a ...
