Improved Power Quality in Battery Chargers for Light Electric Vehicles

This work designs and develops a high-efficiency battery charger with high power factor (BL) DC-DC Cuk converters Electric Vehicle (PF). For electric automobiles, it's a lower cost and greater power charge alternative. This charger contains fewer devices in a single switching cycle, which reduces the additional loss of conduction generated by a typical remediator. The efficiency of the loader thereby increases. The recommended architecture also removes undesired capacitive coupling loops and unwanted conduction via the body diode of the inactive switch in the previously designed BL Cuk converters. This significantly increases the charging efficiency. A flyback converter synchronises the constant current commands (CCs and CVs). The recommended loader utilises AC handles to draw a sinusoidal current and the total harmonic distortion (THD) in the supply current is maintained in accordance with IEC 61000-3-2. In order to validate good charging performance under all operating situations, the proposed charger increased efficiency and PQ indicators are tested.
