  • Abstract

    Advancements in EV battery charging have enhanced overall performance and power quality. Power factor correction (PFC) converters, ‎such as buck, boost, Cuk, Z-source, and Interleaved topologies, minimize ripple and enhance power factor. This study reviews recent ‎charger designs, focusing on PFC converters and their role in reducing ripple and harmonic distortion. It also evaluates constant current (CC) ‎and constant voltage (CV) charging methods through simulations to ensure stable and efficient charging. A 1.4 kW, Level-1 on-board ‎charger was designed to provide 400V DC at 3.5A for a 400V battery pack. Simulations of a modified Cuk converter in CV and CC modes, ‎with a battery, assessed voltage and current stabilization under varying input conditions (180V–280V). PF ranged from 0.87 to 0.97. Additional simulations with a lithium-ion battery analyzed ripple suppression and power factor stability. The results were compared with various ‎past studies on different converter topologies to evaluate performance improvements. Furthermore, the modified converter's results were ‎validated through hardware implementation. The modified Cuk converter maintained a stable 400V, 3.5A output with voltage and current ‎ripple of 4.2% and 4.5%, respectively. The system achieves a PF of 0.983 in CC mode with less than 1% ripple, while CV mode maintains ‎a power factor between 0.940 and 0.946 with a Li-ion battery. The modified Cuk converter outperformed currently available converters, and ‎hardware results aligned closely with PSIM simulation data, confirming reliability and efficient operation. The proposed charger achieves ‎high PF and low ripple, ensuring reliable battery charging‎.
