“…In the non-integrated two-stage OBC shown in Figure 4a, a DC-DC power stage is employed to regulate the DC-link voltage in accordance with the charging profile of the HV battery [100]. This component plays a crucial role in providing galvanic isolation between the HV battery pack and the AC grid, a requirement specified by the UL 2202 and IEC 60950 standards [101].…”

“…A 11 kW two-stage topology is presented in [100], in which a 350 kHz four-channel interleaved totem-pole PFC is used at the single-phase grid side and a 500 kHz three-phase CLLC resonant converter with a primary delta connection is used at the HV battery side (see Figure 9c). To reduce the common-mode noise, Return Path Windings are added to the primary side of the PFC stage.…”

The rising Greenhouse Gas (GHG) emissions stemming from the extensive use of automobiles across the globe represent a critical environmental challenge, contributing significantly to phenomena such as global warming and the deterioration of air quality. To address these challenges, there is a critical need for research and development in electric vehicles (EVs) and their associated charging infrastructure, including off-board and on-board chargers (OBCs). This paper aims to bridge the gaps in existing review literature by offering a comprehensive review of both integrated and non-integrated OBCs for EVs, based on the authors’ knowledge at the time of writing. The paper begins by outlining trends in the EV market, including voltage levels, power ratings, and relevant standards. It then provides a detailed analysis of two-level and multi-level power converter topologies, covering AC-DC power factor correction (PFC) and isolated DC-DC topologies. Subsequently, it discusses single-stage and two-stage non-integrated OBC solutions. Additionally, various categories of integrated OBCs (iOBCs) are explored, accompanied by relevant examples. The paper also includes comparison tables containing technical specifications and key characteristics for reference and analysis.
