Abstract :
In this paper 3.3 kW on-board charger is proposed for electric vehicles or plug-in hybrid electric vehicles. Considering the life time of charger, new topology which is not using the high-voltage electrolytic capacitors is proposed. This charger is comprised of two stages that one is boost converter stage for PFC control and the other is uncontrolled LLC resonant converter for galvanic isolation and step-down of voltage. Proposed charger is implemented and it is 7.1 liters in volume and 6.8kg in weight. The experimental result indicates 92.5% of the efficiency at input voltage 220Vac and 88.3% at input voltage 110Vac under 3.3kW of output power. And the output voltage ranges is from 150 V to 450V.
