Planar transformer technology applied to AC/DC conversion

Abstract

Magnetic components play an important role in the technological evolution towards increased power density of AC/DC power converters. Planar transformers provide several advantages that have to be balanced with the latest evolution of more classical transformer technology. This paper analyses the interest of using planar transformer for AC/DC power conversion. Results of the implementation of a planar transformer in a 600 W AC/DC converter illustrate the analysis.
