In this paper, a front end ac-dc power factor correction topology is proposed for plug-in hybrid electric vehicle (PHEV) battery charging. The topology can achieve improved power quality, in terms of power factor correction, reduced total harmonic distortion at input ac mains, and precisely regulated dc output.

The theoretical analysis of the proposed converter is then developed, while an experimental digital control system is used to implement the new control strategy. A detailed converter operation, analysis and control strategy are presented along with simulation and experimental results for universal ac input voltage (100-240V) to 380V dc output at up to 3.0 kW load and a power factor greater than 0.98. Experimental results show the advantages and flexibilities of the new control method for plug-in hybrid electric vehicle (PHEV) battery charging application.
