Single-stage battery charger for light electric vehicles based on DC-SRC with current boosting circuit

초록

A single-stage battery charger for light electric vehicles to improve lifetime by removing high-voltage electrolytic capacitors is suggested. The proposed charger is based on a diode-clamped series resonant converter equipped with a current-boosting circuit, which increases the power factor by removing dead zones in the line current. The feasibility of the proposed charger has been verified with a 1.7 kW prototype.
