In this paper, a hybrid modulation scheme is proposed for an isolated CLLC converter for a portable EV battery charging system. Wide output voltage (150 V - 950 V) with decent flat efficiency is achieved without additional power processing stage.enBattery chargerOn-Board chargerResonant converterIsolated bidirectional DC-DC converterssoft switchingconference paper
