There are, however, significant challenges to be addressed in terms of cost, performance, reliability and power density. This paper aims at proposing an improved on-board charger architecture taking advantage of a power pulsating buffer topology. The proposed architecture will enable to significantly reduce the dc-link capacitor size, enabling a change in its technology, and leading to a higher power density and higher reliability implementation. The proposed architecture is analyzed, its main design considerations are discussed and, finally, a 3.6-kW experimental prototype is designed and implemented to prove the feasibility of this proposal. As a conclusion, the proposed topology is recommended as a high-performance high-power-density OBC implementation for future EVs. info:eu-repo/grantAgreement/EUR/AEI/TED2021-129274B-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2022-136621OB-I00 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.9 2024 1.852 2024 Electrical and Electronic Engineering 2024 Q1 9.1 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lucía, Oscar Universidad de Zaragoza (orcid)0000-0002-1284-9007 5008 785 Universidad de Zaragoza Dpto.
