Abstract: The rapid adoption of electric vehicles (EVs) has led to an increasing need for efficient battery charging systems with high power quality. In this paper, an improved bridgeless (BL) Cuk converter-based EV battery charger is proposed and analyzed. By eliminating the conventional diode bridge rectifier, the design significantly reduces conduction losses and enhances overall efficiency. The converter is operated in discontinuous conduction mode (DCM), which enables inherent power factor correction (PFC) without requiring complex sensing or control mechanisms. To support effective battery charging, a flyback converter is incorporated, allowing smooth transition between constant current (CC) and constant voltage (CV) modes. The proposed system achieves a near-unity power factor and minimizes total harmonic distortion (THD), ensuring compliance with IEC 61000-3-2 standards. Both simulation and analytical results confirm that the design offers improved efficiency, reduced component count, and better power quality. These features make the proposed charger a suitable and practical solution for modern EV applications.
