The study of the on-board charger with the bridgeless PFC

The efficiency of the charger in the electric vehicle can deeply effect the charging time and the utilization factor of the power source. The efficiency of the on-board charger with the bridgeless PFC can be improved by 2%∼4%. The structure of the charger was designed in the paper. At the same time, the theory of the bridgeless Boost PFC charger was discussed in the paper. The result of the experiment shows that the effective of the charger can be improved about 3% at the least.
