  abstract     = {{Modern battery chargers require AC-DC converters with high input power quality, nearly unity power factor, and low current harmonics to meet grid standards such as IEC 61000-3-2. This paper proposes a two-stage charger topology: a front-end bridgeless interleaved boost PFC converter followed by a synchronous buck DC-DC stage. The interleaved boost stage reduces input current ripple and losses while regulating the DC-link voltage, and the synchronous buck stage supports constant-current/constant-voltage (CC-CV) charging. A closed-loop controller is designed via small-signal modeling of the PFC stage to ensure stable voltage regulation under dynamic conditions. The proposed converter achieves improved power quality (nearly unity input power factor and low input-current THD) without a complex grid-synchronization control algorithm, such as a phase-locked loop (PLL), thereby meeting the IEC 61000-3-2 standard. The simulation results are experimentally supported in a power hardware-in-the-loop (PHIL) laboratory environment, with accurate output-voltage control as predicted theoretically. These results confirm the effectiveness of the bridgeless interleaved boost PFC, cascaded with a synchronous buck architecture, in improving power quality and voltage regulation for battery charging applications.}},
