英文摘要:
      The interleaved Boost PFC topology, which has high power factor and low harmonic current, is adopted as the front stage of the electric vehicle charger to reduce the pollution to the power grid. The designing process and power loss of this circuit have been analyzed in detail. The digital control and the optimized design of hardware reduce the power loss, which can make the high conversion efficiency of PFC converter in all power range. In addition, the requirement of platinum efficiency and the goal of energy saving can be achieved through this design. Finally, a 4kW prototype, which has the advantages of both high power factor and high efficiency in all power, has been built to verify the validity of the design method.
