  • Abstract
    This paper presents an electric vehicle battery charger based on a new LLC converter with two transformers in parallel. This topology achieves zero-voltage switching (ZVS) for main switches in entire load range and zero-current switching (ZCS) for output rectifier diodes under certain conditions. Moreover, the resonant tank consists of two transformers in parallel to avoid high magnetizing current. The proposed charger features a narrow frequency variation range and high efficiencies under various load conditions.
