Abstract:Methodology for directly growing three-dimensional windings on a planar, insulated ferromagnetic core through the process of electroplating and etching is presented in this paper. Designs employing high frequency inductors and transformers built in such a fashion offer tight control over parasitics from sample to sample while achieving higher power density and lower profile compared to other popular planar structures. Further, such structures are believed to be suitable as fundamental building blocks for magne… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
