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. 000132480 536__ $$9info:eu-repo/grantAgreement/EUR/AEI/TED2021-129274B-I00$$9info:eu-repo/grantAgreement/ES/MICINN/PID2022-136621OB-I00 000132480 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000132480 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000132480 700__ $$0(orcid)0000-0002-1284-9007$$aLucía, Oscar$$uUniversidad de Zaragoza 000132480 7102_ $$15008$$2785$$aUniversidad de Zaragoza$$bDpto.
