Abstract: In view of high power factor and high efficiency requirements in electric vehicle charging systems, an improved bridgeless power factor correction based on one-cycle control in the pre-regulator is proposed in this article. First, the working principle of a boost power factor correction converter and a one-cycle control strategy are analyzed. Second, a simulation model is built by MAT-LAB/Simulink (The MathWorks, Natick, Massachusetts, USA), and an experimental plant is developed by electron devices. Finally, simulation and experiment results show that the power factor of the front-end circuit in charging system amounts to more than 0.99, and the total harmonic distortion of current is less than 4%. The efficiency is greatly improved, and pre-stabilized output voltage is achieved. The proposed topology can facilitate the design of the DC/DC circuit in the final stage.
