Literature survey on light electric vehicle battery charger with high-efficiency bridgeless single-power conversion.

Due to the high efficiency and power factor of rechargeable batteries, they require high-power-density and bridgeless single-conversion battery chargers. In this paper, we introduce a bridgeless AC-DC c0nverter that can provide high efficiency and low reverse-recovery losses. The proposed device features a series-resonance current injection system and a linear feedback algorithm to control the output power. Because of the simplicity of the circuit construction, it has a high efficiency and power factor. The suggested charger's theoretical concepts are tested in an actual setting using a 1.7 kW prototype. [ABSTRACT FROM AUTHOR]
