A reduced-part single stage direct AC/DC On-board charger for automotive applications
Abstract
Design of on-board chargers for plug-in electric vehicles (PEVs) is a challenging issue due to size and weight of high-power switching converters, as charging power can be up to 19.2kW in level-2 charging scheme. This paper proposes a reduced-part single stage on-board charger topology, which is integrated to the dc/dc converter used for adjusting voltage levels of battery and dc link during propulsion and regenerative braking. In the proposed topology, one inductor is shared between the dc/dc converter and the charger, eliminating the need for an additional inductor for the charging stage. In charging mode, the proposed interface operates asymmetrical depending on the positive and negative half cycles of the grid. Hence, a charge nonlinear-carrier control method is adopted, and different nonlinear reference voltage waveforms are generated for each half cycles of the grid to ensure unity power factor and stable operation. The operation of the converter is verified through tests carried out for level-1 and level-2 charging and a minimum power factor of 0.99 is achieved at the heavy load condition.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
