| Abstract |
Single-stage on-board chargers for EVs are an attractive solution as they reduce the number ofconverters stages leading to potential increments in power density and cost reduction. Dual-active-bridge (DAB) topologies are particularly attractive for these applications as they offer a largevoltage conversion range, isolation, and relatively simple controllability. Several DAB-basedsingle-stage AC-DC topologies can be found in the literature; however, a comparison of saidtopologies has not been yet been presented. Filling the gap, this paper presents and comparesthe most promising DAB-based topologies used for single-stage OBC applications. For thispurpose, a multi-objective optimization with a Pareto-front is used. Apart from the design ofthe main components, EMI filters are designed for each topology and their size is considered aspart of the evaluation. |
