High-Efficiency High-Density Critical Mode Rectifier/Inverter for WBG-Device-Based On-Board Charger
Open accessAbstract
A widebandgap-based bidirectional on-board charger (OBC) has been proposed with a variable dc-link voltage, which tracks the battery voltage fluctuation. Although this approach is deemed most efficient for the resonant dc/dc stage, it posts significant challenges for the rectifier/inverter stage, which operates in the critical mode to realize zero-voltage switching (ZVS), while subjecting to the large variations of input and output voltages. Design considerations of the ac/dc stage are presented in this paper, including: the evaluation of 1.2-kV SiC MOSFETs; the ZVS extension techniques to realize ZVS under all input/output variations; and a novel universal control strategy for both the rectifier mode and the inverter mode. A prototype is built which achieves 98.5% efficiency at a switching frequency higher than 300 kHz. Furthermore, a 6.6-kW OBC system is demonstrated, using both SiC and GaN devices with 37-W/in3power density and above 96% efficiency.

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.
