“…The buck-boost converter offers reliable solution for the battery charger at sudden varying supply voltage due to both stepping up and stepping down characteristics. A number of PFC converters based on DBR fed and bridgeless (BL) buck-boost configuration such as zeta, single-ended-primary-inductance converter (SEPIC) and Cuk converters, are comprehended in [12][13][14][15][16]. However, the zeta, as well as SEPIC PFC topologies, faces the limitation of discontinuous input current and discontinuous output current.…”

This study proposes an improved electric vehicle (EV) battery charger with a non-inverting output voltage-based bridgeless power factor correction (PFC) Cuk converter and a flyback converter for controlling the battery current in constantcurrent-constant-voltage charging regions. The proposed EV charger eliminates the need for an extra inverse amplifier, which is used for the negative to positive output voltage conversion in a conventional Cuk PFC converter. Therefore, the control of the converter is easy to implement and the cost of the charger is also reduced. Moreover, the design of the charger is proposed for discontinuous conduction mode operation, which comes with the inherent advantages of reduced sensors, low reverse recovery in diodes, and zero current switching. The proposed EV charger, with improved efficiency, operates satisfactorily to comply with the IEC61000-3-2 standard for power quality at steady state and for sudden perturbations in mains voltage.
