Using a Cuk-single-ended primary inductor converter (SEPIC) that is isolated bridgeless (BL), this article
creates a one-stage charger for electric car batteries. When connected to the AC mains, the charger should make
advantage of intrinsic power factor correction (PFC) while running in discontinuous conduction mode. In both
positive and negative cycles, the suggested design beats the BL Cuk converter architecture, although using fewer
components. This is because, in the midpoint of each cycle, SEPIC and Cuk converters are combined. The output is
different from the SEPIC converter that was utilized in both cycles. inductor is included into the Cuk converter side,
which aids in reducing the ripple in the output current. Our novel BL isolated PFC converter was tested with a
single-phase PQ analyzer under a 48 V/100 Ah electric vehicle battery load, and it was found to work with good
power quality (PQ). We build and test the suggested charger to show that it works well with two different charging
profiles. Every possible scenario, from steady-state to extreme-load and line, has its corresponding modeling results
shown. Several performance indicators are documented, including ac mains PF, displacement PF, and mains current
distortion.
