Comparative study of DC/DC electric vehicle charging system with conventional transformer and planar transformer

Abstract

: This paper presents an analysis of electric vehicle charging station operation based on a dual active bridge topology. Two cases are considered: one with the use of a medium frequency planar transformer, the other with a conventional Litz winding trans-former.Ananalysiswasperformedusingbothsolutionsinordertocomparetheperformance characteristics of the system for both cases and to present the differences between each transformer solution. The analysis was based on tests carried out on the full-scale model of an electric vehicle charging station, which is the result of the project "Electric vehicle charging system integrated with lighting infrastructure" realized by the Department of Drives and Electrical Machines,
